Deploy React app with JSON server on Heroku

#react #jsonserver #heroku #tutorial

Prerequisites

Assuming you have already done the following:

Created a react application using create-react-app,
Installed JSON server in the root directory and created db.json database,
Your front-end application can run correctly and can access the JSON database properly,
Your app has been committed on Github,
You have a Heroku account.

Step 1:

create a file named Procfile in the root directory, and paste the following code into the file:

web: node server.js

Step 2:

create a file named server.js in the root directory, and paste the following into the file:

const jsonServer = require("json-server");
const server = jsonServer.create();
const router = jsonServer.router("./db.json");
const middlewares = jsonServer.defaults({
  static: "./build",
});
const PORT = process.env.PORT || 8000;
server.use(middlewares);
server.use(
  jsonServer.rewriter({
    "/api/*": "/$1",
  })
);
server.use(router);
server.listen(PORT, () => {
  console.log("Server is running");
});

Step 3:

(1) Commit the changes above to your Git repo. Then,
(2) Log in to your Heroku account, and create a new app:

(3) In the Deploy catalogue, select GitHub as your Deployment method, find your repo and Connect it to Heroku:

(4) Click Deploy Branch to deploy your app.

Suppose the whole procedure finishes without any problem, congrats! And now, you can click Open app to see your deployed app.

That's the end of this article. I want to share my deployed repo here, and please feel free to check interesting things, play it, fork and give stars, and leave a message below if you have questions.
