8454. Deploying Game Store React App to Netlify

Introduce how to deploy React application to Netlify.

1. Netlify

Netlify is an online service which builds, deploys, and manages modern web projects. Netlify basically initiates its own kind of repository that pushes both to a Github repository and its own services. It offers hosting for front-end projects with many options.

2. Deploying Application From Github Repository

In this tutorial, I will deploy my Game Store React app to Netlify.

2.1 New Netlify Account

Go to https://app.netlify.com/signup to create a Netlify account with your GitHub account.

2.2 New Site from GitHub

After login, you are in the app home page, click ‘New site from Git’. image Choose ‘Github’, next. image Authorize Netlify to access your GitHub account, next. image Choose the repository ‘game-store-react’, next. image Choose master for the Branch to deploy, set npm run build to the Build command, and set dist to the Publish directory, click the ‘Deploy site’ button. image Netlify will start to deploy your site. image Switch to ‘Deploy’ tab to monitor the status and check the logs. image If the deployment fails, click on the FAILED build, check the log and you should see the error in details. image If no issue occurs, the publish will be done after few seconds(or minutes). image

2.3 Testing

Switch back to the ‘Overview’ tab, click on the green link. image Our app is now running in the domain of Netlify. image However, we got ‘Page Not found’ error when access the ‘products’ page. The same error occurs when access the ‘productpage’ page. image Actually, I’ve already discussed this issue in tutorial React Router and Client Side Routing.

2.4 Fixing the Issue

To solve this React Routing issue on Netlify, we need to handling redirects for single page apps, see below. Read more about it in Netlify Document.

Create a file named ‘_redirects’ to the ‘public’ folder of the React project with the following content.

/*    /index.html   200

Then we need this file to be copied to ‘dist’ folder when building. To do so, we can use library ‘copy-webpack-plugin’.

npm i -D copy-webpack-plugin

Edit ‘webpack.parts.js’, add the following codes.

const CopyWebpackPlugin = require("copy-webpack-plugin");

exports.loadStatic = () => ({
  plugins: [
    new CopyWebpackPlugin([
        from: "./public/_redirects",
        to: "./_redirects",
        toType: "file"

Edit ‘webpack.config.js’, call ‘loadStatic’ method in production merge.

const productionConfig = merge([
  // parts.loadEnv('https://online-code-editor-api.herokuapp.com'),
    use: "css-loader"



Run ‘npm run build’. The ‘_redirects’ file is copied from ‘./public’ folder to the root folder of ‘dist’. image In Netlify, switch to ‘Deploy’ tab, click the ‘Trigger Deploy’ button to deploy again. image After the deployment is finished, retry to access the ‘products’ page, it’s working now. image The ‘Add Product’ page also works now. image

2.5 Changing Site Name

Switch to Settings tab, scroll down and click the ‘Change site name’ button. image Change the name to ‘game-store-react’ and save. image Access your site with the new URL, it should work. image

2.6 Hot Module Replacement Error

In addition, I got the following HMR issue somehow after I changed the build command.

VM72 bundle.js:16 Uncaught Error: locals[0] does not appear to be a `module` object with Hot Module replacement API enabled. You should disable react-transform-hmr in production by using `env` section in Babel configuration. See the example in README: https://github.com/gaearon/react-transform-hmr

image The below ‘build’ command triggers this HMR issue.

"build": "webpack --env production ",

To fix the issue, add ‘NODE_ENV=production’ into the build command. Submit the change to Github, Netlify will automatically deploy again, and the HMR issue should be solved.

"build": "NODE_ENV=production webpack --env production ",
