Deploy json-server to Heroku

Instructions how to deploy the full fake REST API json-server to various free hosting sites. Should only be used in development purpose but can act as a simpler database for smaller applications.

Create your database

1 . Clone this repo to anywhere on your computer.

git clone

2 . Change db.json to your own content according to the json-server example and then commit your changes to git.

this example will create /posts route , each resource will have id, title and content. id will auto increment!

      "id" : 0,
      "title": "First post!",
      "content" : "My first content!"

Deploy to Heroku


Heroku is a free hosting service for hosting small projects. Easy setup and deploy from the command line via git.

  • Easy setup
  • Free
Cons (Free Version)
  • App has to sleep a couple of hours every day.
  • "Powers down" after 30 mins of inactivity. Starts back up when you visit the site but it takes a few extra seconds.

Install Heroku

  1. Create your database

  2. Create an account on

  3. Install the Heroku CLI on your computer:

4 . Connect the Heroku CLI to your account by writing the following command in your terminal and follow the instructions on the command line:

heroku login

5 . Then create a remote heroku project, kinda like creating a git repository on GitHub. This will create a project on Heroku with a random name. If you want to name your app you have to supply your own name like heroku create project-name:

heroku create my-cool-project

6 . Push your app to Heroku (you will see a wall of code)

git push heroku master

7 . Visit your newly create app by opening it via heroku:

heroku open

8 . For debugging if something went wrong:

heroku logs --tail

How it works

Heroku will look for a startup-script, this is by default npm start so make sure you have that in your package.json (assuming your script is called server.js):

 "scripts": {
    "start" : "node server.js"

You also have to make changes to the port, you can't hardcode a dev-port. But you can reference herokus port. So the code will have the following:

const port = process.env.PORT || 4000;
