json-server is not recognized as an internal or external command

Question

I am setting up a json-server and I install it and assign it to be my npm start command like so

"scripts": {
    "start": "json-server -p 3001 -w db.json"

but every time I type npm start on the terminal I got this error

> [email protected] start C:\Work\React-projects\streams\api-server
> json-server -p 3001 -w db.json

'json-server' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! code ELIFECYCLE

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Answer 1

First, you need to check json-server installed globally or not. or you can install it globally by

npm install -g json-server

If you install it locally in your project, use npx to run it

npx json-server --watch db.json

Checkout difference between npx and npm here: https://stackoverflow.com/a/52018825/11285186

Answer 2

First step you install the json server using the following command:
npm install -g json-server
Then, you can run the command and select the port using the following command:
npx json-server --watch -p 3333 server.json
Change 3333 to the port number you want and replace server.json with the name of your fake api.

In my case, I'm using React js and my server.json is at the root of my application.
