A production-ready JSON file, and more information on code signing can be found on Nick Parson’s article. Before we can start building our electron application we first need to install a few dependencies and define our project structure.
We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. You’ll have them listed in DevDependencies instead, so that way your local app functions normally. For example, Visual Studio code, try to guess what is powering it ;). A brief introduction to exporting our React-App with Electron. Less confusion — the better. Overview¶ Modern web development practices today require a lot of setup with things like webpack to bundle your code, babel for transpiling, eslint for linting, and so much more that the list just goes on.
developers. Before we get started, let me tell you about Electron and React, and why create-react-app is such a great tool. A native desktop app running React inside of it.
For (2), we can add a simple node script (electron-wait-react.js) that waits for the React dev server to start, then starts Electron. I’ll show you the quick answer for Mac users who want to create the .exe counterpart.
Webpack processes each entry point by passing the file (and its dependencies) through a loader. Stay safe, friends. Loaders are selected via rules, often with a loader per file extension. In the electron-pack, you’ll see tutorials out there that will mention -em instead of -c.extraMedatada. Ejecting an application copies all the encapsulated configuration of create-react-app to the your project, providing a boilerplate configuration that you can change as you wish. Now you’re ready to delve into the Electron + Electron Builder docs to take the next step. If nothing happens, download Xcode and try again. Next we’ll set up Webpack to optimize our application. This code snippet is essentially telling Webpack where our entry file is, where we want to output, and using what modules and plugins. Electron has two separate processes: a main process, which is Electron itself, and a render process, which is essentially a web page that Electron loads in a Chromium-based browser. A blog post by Rui Figueiredo ignited my interest in Electron.
For example, you might want to access the local file system or use Electron’s ipcRenderer.
This configuration is similar to that of our main process, but there are some new items: Since the output path for our renderer files is no longer the src directory, we’ve instructed Webpack to put our resources in a new dist directory. It hides most of the configuration and lets the developer use simple commands, such as npm start and npm run build to run and build their apps. Last Updated Aug 21, 2020. To be honest, I had trouble compiling my own Electron project with React, so I simplified everything down to this boilerplate template. to start our Electron application. electron-webpack ¶ Because setting up webpack in the electron environment shouldn’t be difficult. Go ahead and build a brand new React app running create-react-app in your terminal. In our Scripts, we’ll need to add a few more: Preelectron-pack runs a build every time you compile your App for distribution. The complete code for this example can be found here on GitHub.
React will first render in your browser, but then your second command should bring up Electron with your React-App.
Because…we no longer want to render an index.html file…that we haven’t created. React is Facebook’s JavaScript view framework. Scroll back up for the code if needed. Mission accomplished. I was drawn to the idea of using create-react-app because it hides the webpack configuration details. To install react, make sure you have the latest node.js and npm installed in your machine. What You’ll see that the string is not a URI.
You’ll also find: But I’ve found that I don’t have to declare “win” in order to get a functioning .exe file.
You should see something similar to me: This is running without our localhost! Simply run the following: Your terminal will be busy for a few minutes. videos, articles, and interactive coding lessons - all freely available to the public. This is merely an introduction to exporting our newly created app. Rather than pasting my whole JSON file for you to parse out the differences, I’ll explain what I added one at a time. If you don’t include this preelectron-pack, you will get errors and you won’t be able to export.
We did it!
This story is published in Noteworthy, where 10,000+ readers come every day to learn about the people & ideas shaping the products we love. If not, you can just copy the files in the ./src directory from the GitHub repo and follow one of these tutorials if you’d like to learn more. There are more in-depth concepts that we need to know to fully integrate React with Electron and get this app ready for production. react: npm startelectron: node src/electron-wait-react . We can execute npm webpack --mode production to compile and then node electron . Here’s the code for steps 3 and 4: When you run the npm commands in step 7, you should see this: You can make live changes to the React code and you should see them reflected in the running Electron app. We need to add the homepage to our JSON file, otherwise, even if everything else renders correctly — Electron has no idea where your CSS/JS files are kept. The configuration overhead varies (more on this later), and there are many boilerplate and application generators available, but in July 2016 Facebook Incubator released a tool, create-react-app.
The C# what? Here’s the GitHub repo for my app. The process for building for multiple platforms gets more complicated. If the env var exists, we’ll use it; else we’ll use the production static HTML file. We’ll add this in our package.json as a script.
We’re also installing path as a production dependency cause we will be using it in with Electron later. This will fail when loading it in Electron. React will first render in your browser, but then your second command should bring up Electron with your React-App. Design, JavaScript Electron and React. Learn more.
And Electron is GitHub’s framework for building cross-platform desktop apps in JavaScript. You can always update your selection by clicking Cookie Preferences at the bottom of the page. Now we need to compile our React project down into a single bundle, for this we will use Webpack. Electron will default their logo in place of custom icons. And that’s it! You just made your first Electron application. We’re also telling our build the required files, and redirecting it to our assets folder to find those icons (if you elected to include them). That deals with (1). I’m not going to be making anything spectacular in this example. The React app is a basic counter where you can increase or decrease a number by clicking the buttons. So we run the following in our terminal with our new setup: & (after your React-App displays in your browser). Contact us to discuss how we can help! So, electron-wait-react.js subtracts 100 to set the port number of the React dev server correctly. We’ll need to include the electron-start script that we had included from our first demo.
and staff. Tweet Learn more. But, Electron is clearly here to stay and it’s not mandatory that your app should feel slow and consume tons of memory, like VS Code demonstrates every day to me (on a not blazing fast machine).
