Json-server: how to work with many json files together?

[bi-kai]

I have more than 10 json files in one project.
Different file is using for different purpose, i don't want to join them into one file.
How to work with all of them in json-server?

[simeg]

@bi-kai To me it sounds like you want to use your files like one file but that the concatenation is handled by json-server and not by you, is that assumption correct?

[yairEO]

@simeg - doesn't sound like that to me. I have the same situation and I don't want a single file. I want each route to fetch a different JSON file

[bi-kai]

@simeg communications between frontend and backend with RESTful API in my APP, i mock each one with individual json file which named by RESTful interface name. i really donot want to join json files together.

Why don't you use something like:

db.js

var firstRoute  = require('./jsonfile1.json');
var secondRoute = require('./jsonfile2.json');
var thirdRoute  = require('./jsonfile3.json');
var fourthRoute = require('./jsonfile4.json');
// and so on

module.exports = function() {
return {
firstRoute  : firstRoute,
secondRoute : secondRoute,
thirdRoute  : thirdRoute, 
fourthRoute : fourthRoute
// and so on
}
}

server.js

var jsonServer  = require('json-server')
var server      = jsonServer.create()
var router      = jsonServer.router('./db.js')
var middlewares = jsonServer.defaults()

server.use(middlewares)
server.use(router)
server.listen(3000, function () {
  console.log('JSON Server is running')
})

command line

node server.js

Hi,
@Nilegfx this option seems user friendly, sadly this doesn't seem to work.

When starting node, this craches complaining about

SyntaxError: Malformed JSON in file: ./tata.js
Unexpected token 'v' at 1:1
var firstRoute  = require('./jsonfile1.json');

Is there a way to provider a js file to jsonServer.router()?

[semagarcia]

Hi,

@agouriou I'm providing a .js file to the router in that way:

var jsonServer  = require('json-server');

var server      = jsonServer.create();
var router      = jsonServer.router(require('./jsonServer.js')());
var middlewares = jsonServer.defaults();

server.use(middlewares);
server.use(router);
server.listen(5000, function () {
  console.log('JSON Server is running');
});

The "jsonServer.js" is a file I've developed to read all my .json files from a specific folder and merge all of them into one.

Notice the fact that those js file should returns a json file.

I hope it helps you. If doesn't work, please, let me know.

[agouriou]

Thanks @semagarcia , I used something like this.

@semagarcia i use your solution and it work very great. But i have one thing to ask? How can i make a fake data like using https://github.com/marak/Faker.js ?
Thank you.

Below is peace of code worked for me in

1. Routing dynamic resource to static content (let say images)
2. Watching multiple db.json file like db-1.json, db-2.json and so on and getting accumulated response form common port

//db.js
module.exports = function () {
return Object.assign({},
require('./db-1.json'),
require('./db-2.json'),
require('./db-3.json')
);
}

// router.js
var jsonServer = require('json-server')
var demodata = require('./data/db.js')()
var server_port = 4000;

var router = jsonServer.router(demodata)
var server = jsonServer.create()

/**

• All image related routing
  */
  server.use(jsonServer.rewriter({
  '/image/:id': '/assets/images/Img_1.png'
  }))

server.use(jsonServer.defaults(['./public'])) //for static files
server.use(router)

server.listen(server_port, () => {
console.log('**************');
console.log('* ');
console.log(' Json Server is Up & Running at port ' + server_port + ' ');
console.log(' ');
console.log('***************');
});

Now run 'node .js'
http://localhost:4000//
http://localhost:4000//
http://localhost:4000/image/1 will open image as response

Note: Do not trust much command line instruction like

1. --static
2. --route
3. --configuration

Better to give try with 'JS' file. above instruction killed my 2 days.

Feel free for any doubt and clarification

How to pass server instance to routes.js so that we refer server.get('route', someapi); inside routes.js or any close solution to it?

@semagarcia @agouriou First of all thanks for the solution, But for me after doing the post or put operations it is not updating ( persisting ) the data to json file, is there something i am missing here?

I am also facing the same issue. While posting a request it is not updating the corresponding .json file.
