How to Integrate Mailchimp Forms in a React Project

Intro

Today we will cover how to set up an email signup form using React and Mailchimp. This blog will be using the starter.dev cra-rxjs-styled-components template to expedite the process. This article assumes you have a basic understanding of React, and have set up a Mailchimp account. Here is the code repo if you want to review it while reading, or just skip ahead. We will start with setting up our React project using Starter.dev for simplicity, and then finish it up by integrating the two for our signup form.

To start, we will be using the command yarn create @this-dot/starter --kit cra-rxjs-styled-components, which can be found here. We’ll go ahead, and give the project a name. I will be calling mine react-mailchimp.

Now we will navigate into the project and do a yarn install. Then we can run yarn run dev to get it up and running locally on localhost:3000. This should have us load up on the React App, RxJS, and styled-components Starter kit page.

With that all set, we’ll also need to install jsonp by using yarn add jsonp. We’ll be using jsonp instead of fetch to avoid any CORS issues we may run into. This also makes for an easy and quick process by not relying on their API, which can’t be utilized by the client.

Now that we have our project set up, we will go ahead and go and grab our form action URL from MailChimp. This can be found by going to your Audience > Signup Forms > Embedded Forms > Continue and then grabbing the form action URL found in the Embedded Form Code. We need to make a small change to the URL and swap /post? with /post-json?.

We can now start setting up our form input, and our submit function. I will add a simple form input and follow it up, and a submit function. Inside the submit function, we will use our imported jsonp to invoke our action URL.

import { useState } from 'react';
import jsonp from 'jsonp';

export const MailChimp = () => {
 const [email, setEmail] = useState('');

 const onSubmit = (e: any) => {
   e.preventDefault();
   const url = 'insert-mailchimp-action-url-here';
   jsonp(`${url}&EMAIL=${email}`, { param: 'c' }, (_: any, data: any) => {
     console.log('data', data);
     const { msg } = data;

     alert(msg);
   });
 };

 return (
   <div>
     <form onSubmit={onSubmit}>
       <label>Email</label>
       <input
         type="email"
         name="EMAIL"
         required
         onChange={(e) => setEmail(e.target.value)}
       ></input>
       <button type="submit">Submit</button>
     </form>
   </div>
 );
};

We’ll also add a quick alert to let the user know that it was successful and that’s it! We’ve now successfully added the email to our MailChimp account.

Building a Multi-Response Streaming API with Node.js, Express, and React

Introduction As web applications become increasingly complex and data-driven, efficient and effective data transfer methods become critically important. A streaming API that can send multiple responses to a single request can be a powerful tool for handling large amounts of data or for delivering real-time updates. In this article, we will guide you through the process of creating such an API. We will use video streaming as an illustrative example. With their large file sizes and the need for flexible, on-demand delivery, videos present a fitting scenario for showcasing the power of multi-response streaming APIs. The backend will be built with Node.js and Express, utilizing HTTP range requests to facilitate efficient data delivery in chunks. Next, we'll build a React front-end to interact with our streaming API. This front-end will handle both the display of the streamed video content and its download, offering users real-time progress updates. By the end of this walkthrough, you will have a working example of a multi-response streaming API, and you will be able to apply the principles learned to a wide array of use cases beyond video streaming. Let's jump right into it! Hands-On Implementing the Streaming API in Express In this section, we will dive into the server-side implementation, specifically our Node.js and Express application. We'll be implementing an API endpoint to deliver video content in a streaming fashion. Assuming you have already set up your Express server with TypeScript, we first need to define our video-serving route. We'll create a GET endpoint that, when hit, will stream a video file back to the client. Please make sure to install cors for handling cross-origin requests, dotenv for loading environment variables, and throttle for controlling the rate of data transfer. You can install these with the following command: ` yarn add cors dotenv throttle @types/cors @types/dotenv @types/throttle ` `typescript import cors from 'cors'; import 'dotenv/config'; import express, { Request, Response } from 'express'; import fs from 'fs'; import Throttle from 'throttle'; const app = express(); const port = 8000; app.use(cors()); app.get('/video', (req: Request, res: Response) => { // Video by Zlatin Georgiev from Pexels: https://www.pexels.com/video/15708449/ // For testing purposes - add the video in you static` folder const path = 'src/static/pexels-zlatin-georgiev-15708449 (2160p).mp4'; const stat = fs.statSync(path); const fileSize = stat.size; const range = req.headers.range; if (range) { const parts = range.replace(/bytes=/, '').split('-'); const start = parseInt(parts[0], 10); const end = parts[1] ? parseInt(parts[1], 10) : fileSize - 1; const chunksize = end - start + 1; const file = fs.createReadStream(path, { start, end }); const head = { 'Content-Range': bytes ${start}-${end}/${fileSize}`, 'Accept-Ranges': 'bytes', 'Content-Length': chunksize, 'Content-Type': 'video/mp4', }; res.writeHead(206, head); file.pipe(res); } else { const head = { 'Content-Length': fileSize, 'Content-Type': 'video/mp4', }; res.writeHead(200, head); fs.createReadStream(path).pipe(res); } }); app.listen(port, () => { console.log(Server listening at ${process.env.SERVER_URL}:${port}`); }); ` In the code snippet above, we are implementing a basic video streaming server that responds to HTTP range requests. Here's a brief overview of the key parts: 1. File and Range Setup__: We start by determining the path to the video file and getting the file size. We also grab the range header from the request, which contains the range of bytes the client is requesting. 2. Range Requests Handling__: If a range is provided, we extract the start and end bytes from the range header, then create a read stream for that specific range. This allows us to stream a portion of the file rather than the entire thing. 3. Response Headers__: We then set up our response headers. In the case of a range request, we send back a '206 Partial Content' status along with information about the byte range and total file size. For non-range requests, we simply send back the total file size and the file type. 4. Data Streaming__: Finally, we pipe the read stream directly to the response. This step is where the video data actually gets sent back to the client. The use of pipe() here automatically handles backpressure, ensuring that data isn't read faster than it can be sent to the client. With this setup in place, our streaming server is capable of efficiently delivering large video files to the client in small chunks, providing a smoother user experience. Implementing the Download API in Express Now, let's add another endpoint to our Express application, which will provide more granular control over the data transfer process. We'll set up a GET endpoint for '/download', and within this endpoint, we'll handle streaming the video file to the client for download. `typescript app.get('/download', (req: Request, res: Response) => { // Again, for testing purposes - add the video in you static` folder const path = 'src/static/pexels-zlatin-georgiev-15708449 (2160p).mp4'; const stat = fs.statSync(path); const fileSize = stat.size; res.writeHead(200, { 'Content-Type': 'video/mp4', 'Content-Disposition': 'attachment; filename=video.mp4', 'Content-Length': fileSize, }); const readStream = fs.createReadStream(path); const throttle = new Throttle(1024 1024 * 5); // throttle to 5MB/sec - simulate lower speed readStream.pipe(throttle); throttle.on('data', (chunk) => { Console.log(Sent ${chunk.length} bytes to client.`); res.write(chunk); }); throttle.on('end', () => { console.log('File fully sent to client.'); res.end(); }); }); ` This endpoint has a similar setup to the video streaming endpoint, but it comes with a few key differences: 1. Response Headers__: Here, we include a 'Content-Disposition' header with an 'attachment' directive. This header tells the browser to present the file as a downloadable file named 'video.mp4'. 2. Throttling__: We use the 'throttle' package to limit the data transfer rate. Throttling can be useful for simulating lower-speed connections during testing, or for preventing your server from getting overwhelmed by data transfer operations. 3. Data Writing__: Instead of directly piping the read stream to the response, we attach 'data' and 'end' event listeners to the throttled stream. On the 'data' event, we manually write each chunk of data to the response, and on the 'end' event, we close the response. This implementation provides a more hands-on way to control the data transfer process. It allows for the addition of custom logic to handle events like pausing and resuming the data transfer, adding custom transformations to the data stream, or handling errors during transfer. Utilizing the APIs: A React Application Now that we have a server-side setup for video streaming and downloading, let's put these APIs into action within a client-side React application. Note that we'll be using Tailwind CSS for quick, utility-based styling in our components. Our React application will consist of a video player that uses the video streaming API, a download button to trigger the download API, and a progress bar to show the real-time download progress. First, let's define the Video Player component that will play the streamed video: `tsx import React from 'react'; const VideoPlayer: React.FC = () => { return ( Your browser does not support the video tag. ); }; export default VideoPlayer; ` In the above VideoPlayer component, we're using an HTML5 video tag to handle video playback. The src attribute of the source tag is set to the video endpoint of our Express server. When this component is rendered, it sends a request to our video API and starts streaming the video in response to the range requests that the browser automatically makes. Next, let's create the DownloadButton component that will handle the video download and display the download progress: `tsx import React, { useState } from 'react'; const DownloadButton: React.FC = () => { const [downloadProgress, setDownloadProgress] = useState(0); const handleDownload = async () => { try { const response = await fetch('http://localhost:8000/download'); const reader = response.body?.getReader(); if (!reader) { return; } const contentLength = +(response.headers?.get('Content-Length') || 0); let receivedLength = 0; let chunks = []; while (true) { const { done, value } = await reader.read(); if (done) { console.log('Download complete.'); const blob = new Blob(chunks, { type: 'video/mp4' }); const url = window.URL.createObjectURL(blob); const a = document.createElement('a'); a.style.display = 'none'; a.href = url; a.download = 'video.mp4'; document.body.appendChild(a); a.click(); window.URL.revokeObjectURL(url); setDownloadProgress(100); break; } chunks.push(value); receivedLength += value.length; const progress = (receivedLength / contentLength) 100; setDownloadProgress(progress); } } catch (err) { console.error(err); } }; return ( Download Video {downloadProgress > 0 && downloadProgress Download progress: )} {downloadProgress === 100 && Download complete!} ); }; export default DownloadButton; ` In this DownloadButton component, when the download button is clicked, it sends a fetch request to our download API. It then uses a while loop to continually read chunks of data from the response as they arrive, updating the download progress until the download is complete. This is an example of more controlled handling of multi-response APIs where we are not just directly piping the data, but instead, processing it and manually sending it as a downloadable file. Bringing It All Together Let's now integrate these components into our main application component. `tsx import React from 'react'; import VideoPlayer from './components/VideoPlayer'; import DownloadButton from './components/DownloadButton'; function App() { return ( My Video Player ); } export default App; ` In this simple App component, we've included our VideoPlayer and DownloadButton components. It places the video player and download button on the screen in a neat, centered layout thanks to Tailwind CSS. Here is a summary of how our system operates: - The video player makes a request to our Express server as soon as it is rendered in the React application. Our server handles this request, reading the video file and sending back the appropriate chunks as per the range requested by the browser. This results in the video being streamed in our player. - When the download button is clicked, a fetch request is sent to our server's download API. This time, the server reads the file, but instead of just piping the data to the response, it controls the data sending process. It sends chunks of data and also logs the sent chunks for monitoring purposes. The React application collects these chunks and concatenates them, displaying the download progress in real-time. When all chunks are received, it compiles them into a Blob and triggers a download in the browser. This setup allows us to build a full-featured video streaming and downloading application with fine control over the data transmission process. To see this system in action, you can check out this video demo. Conclusion While the focus of this article was on video streaming and downloading, the principles we discussed here extend beyond just media files. The pattern of responding to HTTP range requests is common in various data-heavy applications, and understanding it can be a useful tool in your web development arsenal. Finally, remember that the code shown in this article is just a simple example to demonstrate the concepts. In a real-world application, you would want to add proper error handling, validation, and possibly some form of access control depending on your use case. I hope this article helps you in your journey as a developer. Building something yourself is the best way to learn, so don't hesitate to get your hands dirty and start coding!...

Setting Up React Navigation in Expo Web: A Practical Guide cover image

Setting Up React Navigation in Expo Web: A Practical Guide

Introduction We have come a long way from the days where we had to write different code for different platforms. Today, we can write code once and run it anywhere using technologies like React Native. React Native is a framework that allows us to write native apps for Android, iOS, and the web, using JavaScript and React. This makes it more interesting for teams that want to cut time/development cost to look into it. We recently launched our Expo-Zustand-Styled Components showcase app here at This Dot Labs. We also showcased how we can use expo`, `zustand`, and `styled-components` to build a React Native app that can run on Android, iOS, and the web all in one codebase. In this article, we will be looking at React Navigation, how to configure Deep Linking to navigate to different screens, and handling dynamic routes paths in our app. We'll do this by looking at the challenges we had to deal with while working on our showcase app, especially when running the app on the web. Getting started Before we dive in, we need to install all the needed dependencies. Let's make sure we have the expo cli installed. We can do this by running the following command: `bash npm i expo-cli ` We can now Initialize a new Expo app`. We can do this by running the following command: `bash npx create-expo-app rn-web-routing ` Next, we need to install the navigation package, and since we are also building this app for the web, we need to install the needed dependencies. `bash npx expo install @react-navigation/native @react-navigation/native-stack react-dom react-native-web @expo/webpack-config ` You can also leverage our expo-zustand-styled-component starter kit, which offers all configurations to build for IOS, Android, and the web. Setting up the navigation Let's set up our navigation routes. We will use native-stack` for our navigation. We can do this by creating a `navigation` folder in our `src` folder, and creating an `index.ts` file in it. This will contain our root navigator. `js import { createNativeStackNavigator } from "@react-navigation/native-stack"; import React from "react"; // import screens const Stack = createNativeStackNavigator(); const Routes = () => { return {/ screens stack */}; }; export default Routes; ` We can now import our Routes` component in our `App.tsx` file and render it. `js import React from 'react'; import Routes from './navigation'; export default function App() { return ( {/ ... other config eg provider */} {/ ... other config eg provider */} ); } ` Creating our screens We can now create our screens. We will create a screens` folder in our `src` folder and a `Home.tsx` file in it which will contain our home screen. `js import React from "react"; import { View, Text } from "react-native"; const Home = () => { return ( This is Home ); }; export default Home; ` We can now import our Home` component in our `Routes` component, and add it to our stack. `js import { createNativeStackNavigator } from "@react-navigation/native-stack"; import React from "react"; import Home from "../screens/Home"; const Stack = createNativeStackNavigator(); const Routes = () => { return ( ); }; export default Routes; ` We can now do the same for the other screens we want to add to our stack. Deep linking During the development of the expo showcase kit, we faced an issue on the web. When we navigate to a page, the URL in the browser still remains in the index. This is because we have not configured deep linking. Deep Linking is a way to navigate to different screens in our app using a custom URL link. This is very useful when we want to have individual URLs for each of our pages. This is also useful when we want to share a link to a specific screen in our app, saving the user time and energy in locating a particular page themselves. We can do this by creating a config file in our navigation folder with the following code. `js import { NavigationContainer } from "@react-navigation/native"; import as Linking from "expo-linking"; const linking = { prefixes: [Linking.createURL("/")], // this is the prefix for our app. Could be anything eg https://myapp.com config: { screens: { Home: "", // ... other screens }, }, }; export default linking; ` And then we can import our linking` config in our `App.tsx` file and pass it to the `NavigationContainer`. `js export default function App() { return ( {/ ... other config eg provider */} {/ ... other config eg provider */} ); } ` We will come back to this config file later as we are going to deep dive into more complex routing, and how to handle it. Let's run our app now, and see how it works. Running the app Now, we can run our app. We can do this by running the following command: `bash expo start ` Press w` to open it on a web browser, you should see something like this: We can see we are in our index page which is the home page, we can now navigate to the eg Profile` page by clicking the button on the home page. To have your preferred page url path, we need to update the linking config with the appropriate page URL. Otherwise, deep linking will use the screen name as the page URL. Handling dynamic routes Say you want to have a page that can be accessed by different users. You can do this by passing the user id as a parameter in the URL. This is called dynamic routing. We can do this by updating our linking` config file with the following code. ` import { NavigationContainer } from "@react-navigation/native"; import as Linking from "expo-linking"; const linking = { prefixes: [Linking.createURL("/")], config: { screens: { Home: "", Profile: "profile/:id", // ... other screens }, }, }; export default linking; ` This will allow us to access the Profile` page by passing the user id as a parameter in the URL. We can now update our `Profile` page to get the user id from the URL and display it. `js import React from "react"; import { View, Text } from "react-native"; import { useRoute } from "@react-navigation/native"; const Profile = () => { const route = useRoute(); const { id } = route.params; return ( This is Profile User id: {id} ); }; export default Profile; ` During the development of our showcase app, we were faced with an issue. We needed to replicate a route /tree/main/a/b/c` with a pattern as `/tree/:branch/:path*`, where the path is `a/b/c`just like we have in other showcases. `js import { NavigationContainer } from "@react-navigation/native"; import as Linking from "expo-linking"; const linking = { prefixes: [Linking.createURL("/")], config: { screens: { Home: "", Profile: "profile/:id", Tree: "tree/:branch/:path", // ... other screens }, }, }; export default linking; ` This didn't work as expected. But on further investigation, we found out that we have to manually handle this route in the getStateFromPath of the linking configuration file, by updating the state and returning it. `js import { getStateFromPath } from "react-native"; import { NavigationContainer } from "@react-navigation/native"; import as Linking from "expo-linking"; const linking = { prefixes: [Linking.createURL("/")], config: { screens: { Home: "", Profile: "profile/:id", Tree: "tree/:branch/:path", // ... other screens }, }, getStateFromPath(path, options) { let state = getStateFromPath(path, options); // If the state is undefined, it means that the path doesn't match any route in our config, and // we want to handle the path ourselves to the right screen, by updating the state and returning it. if (!state) { // check if route contains the main identifier of the screen we want to show const isTree = path.includes("tree"); if (isTree) { const [, , branch, ...rest] = path.split("/"); state = { routes: [ { path, name: "Tree", params: { branch, path: rest.join("/"), // here, our path is the rest of the path after the branch }, }, ], }; } } return state; }, }; export default linking; ` With these configurations, we can now navigate throughout our app using the Link component from react-navigation/native`. `js import React from "react"; import { View, Text } from "react-native"; import { Link } from "@react-navigation/native"; const Home = () => { return ( This is Home ); }; ` To make use of the path` parameter in our `Tree` page: `js import React from "react"; import { View, Text } from "react-native"; const Tree = ({ route }) => { const { branch, path } = route.params; return ( This is Tree Branch: {branch} Path: {path} ); }; export default Tree; ` Conclusion In this article, we have seen how to set up our navigation in our expo app using react-navigation/native`. We have also seen how to configure deep linking, which will help us to navigate through our app using the URL path. Next, we've learned how to handle dynamic routes, which will help us pass parameters in the URL path, and handle some special cases like the one we had with the `Tree` page. If you have any questions or run into any trouble, feel free to join the discussions going on at starter.dev or on our Discord....

Setting Up a Shopify App: Updating Customer Orders with Tracking Info  cover image

Setting Up a Shopify App: Updating Customer Orders with Tracking Info

Today, we are wrapping up our adventure! Last time we learned about retrieving fulfillment IDs, but this time, we encounter the final boss: updating customer orders with tracking information. Now, if we have any new adventurers with us, I recommend heading over here to prep yourself for the encounter ahead. If you just need a recap of our last session, you can head over here. Alternatively, if you just want the code from last time that can be found here. If you want to skip ahead and look at the code it can be found here. With that all said we’re off to battle with updating customer orders with tracking information! Body We’re gonna start by heading over to our app/routes/app.index.jsx file, and grabbing the code found in the loader function. We’ll be moving that to our action function so we can add our post call. We’ll completely replace the existing action function code, and because of that, we need to make a couple of tweaks to the code base. We’re going to remove anything that has a reference to actionData?.product` or `productId`. Now what we need to add the call admin.rest.resources.Fulfillment, which will allow us to update customer orders with tracking information. We’ll be placing it under our fulfillment ID loop. Here is a general example of what that call will look like. `js const fulfillment = new admin.rest.resources.Fulfillment({ session: session, }); ` This is a good start as we now have our fulfillment information and get to add a few things to it. We’ll start off by adding our fulfillment ID and then our fulfillment tracking info. `js fulfillment.lineitems_by_fulfillment_order = [ { Fulfillmentorder_id: , }, ]; fulfillment.trackinginfo = { company: , number: , }; ` Awesome! Now we have given the fulfillment ID and tracking info we need to the fulfillment object, but we need to do one more thing for that to update. Thankfully, it’s a small thing and that’s to save it. `js await fulfillment.save({ update: true, }); ` Now, the above will work wonderfully for a single order, but based on our prior adventurers, we had multiple ids for orders that needed to be completed. So our next step is to loop over our fulfillment object. Though before we do that, here is what the current code should look like: `js const fulfillment = new admin.rest.resources.Fulfillment({ session: session, }); fulfillment.lineitems_by_fulfillment_order = [ { Fulfillmentorder_id: , }, ]; fulfillment.trackinginfo = { company: , number: , }; await fulfillment.save({ update: true, }); ` Before we go to loop over this, we’re going to add a small change to fulfillmentIds. We’re going to create a new variable and add the company and tracking number information. So above the fulfillment variable, we will add this: `js const fulfillmentIdsComplete = fulfillmentIds.map((item) => { item.company = "USPS"; item.trackingNumber = "1Z001985YW99744790"; }); ` Perfect! Now for the looping, we’ll just wrap it in a for of loop: `js for (const fulfillmentIdComplete of fulfillmentIdsComplete) { const fulfillment = new admin.rest.resources.Fulfillment({ session: session, }); fulfillment.lineitems_by_fulfillment_order = [ { Fulfillmentorder_id: fulfillmentIdComplete.id, }, ]; fulfillment.trackinginfo = { company: fulfillmentIdComplete.company, number: fulfillmentIdComplete.trackingNumber, }; await fulfillment.save({ update: true, }); } ` Now that the loop is set up, we will be able to go through all of the orders and update them with the shipping company and a tracking number. So we’ll run a yarn dev, and navigate to the app page by pressing the p button. We should see our template page, and be able to click on the Generate a product button. Now we’ll navigate to our order page and we should see all open orders set to fulfilled. Conclusion Here we are. At the end of our three part saga, we covered a fair share of things in order to get our customer orders tracking information added, and can now take a long rest to rejuvenate....

This tool is crucial for SEO and social media presence, as it previews the Open Graph tags (like images and descriptions) used when your app is shared. No more deploying first to check if everything looks right – you can now tweak and get instant feedback within the DevTools. This feature not only streamlines the process of optimizing for social media but also ensures your app makes the best possible first impression online. Timeline The Timeline feature in Nuxt DevTools is another standout tool. It lets you track when and how each part of your app (like composables) is called. This is different from typical performance tools because it focuses on the high-level aspects of your app, like navigation events and composable calls, giving you a more practical view of your app's operation. It's particularly useful for understanding the sequence and impact of events and actions in your app, making it easier to spot issues and optimize performance. This timeline view brings a new level of clarity to monitoring your app's behavior in real-time. Production Build Analyzer The Production Build Analyzer feature in Nuxt DevTools v1.0 is like a health check for your app. It looks at your app's final build and shows you how to make it better and faster. Think of it as a doctor for your app, pointing out areas that need improvement and helping you optimize performance. API Playground The API Playground in Nuxt DevTools v1.0 is like a sandbox where you can play and experiment with your app's APIs. It's a space where you can easily test and try out different things without affecting your main app. This makes it a great tool for trying out new ideas or checking how changes might work. Some other cool features Another amazing aspect of Nuxt DevTools is the embedded full-featured VS Code. It's like having your favorite code editor inside the DevTools, with all its powerful features and extensions. It's incredibly convenient for making quick edits or tweaks to your code. Then there's the Component Inspector. Think of it as your code's detective tool. It lets you easily pinpoint and understand which parts of your code are behind specific elements on your page. This makes identifying and editing components a breeze. And remember customization! Nuxt DevTools lets you tweak its UI to suit your style. This means you can set up the tools just how you like them, making your development environment more comfortable and tailored to your preferences.
