json-server-reset

Reset middleware for json-server

NPM

Build status semantic-release js-standard-style Cypress.io tests renovate-app badge

Install

Requires Node version 8 or above (because of json-server@0.15 peer dependency).

npm install --save json-server-reset

Use

If you are using json-server, add this module as a middleware. For example, imagine our data file to be data.json with the following resources

{
  "todos": []
}

Then load the file and this middleware

json-server data.json --middlewares ./node_modules/json-server-reset

Then you can work with "todos" and reset the datastore (I am using httpie client in this examples)

$ http :3000/todos
[]
$ http POST :3000/todos text="do something"
{
    "id": 1,
    "text": "do something"
}
$ http POST :3000/todos text="do something else"
{
    "id": 2,
    "text": "do something else"
}
$ http :3000/todos
[
    {
        "id": 1,
        "text": "do something"
    },
    {
        "id": 2,
        "text": "do something else"
    }
]

Now reset the database back to the initial empty list of todos. Note := syntax to send the JSON as a list, not as a string.

$ http POST :3000/reset todos:=[]
$ http :3000/todos
[]

Debugging

Run this module with environment variable

DEBUG=json-server-reset

Using in your own server

If you want to use json-server-reset when building your own server that includes json-server, make sure the to initialize it by passing json-server reference and router database reference, and to add body-parser middleware before the reset. This middleware is included with json-server

Then set it to be the middleware before the rest of the json-server middlewares.

const jsonServer = require('json-server')
const reset = require('json-server-reset')
const setApp = require('json-server-reset/src/set-app')
const bodyParser = require('json-server/lib/server/body-parser')
 
// create json server and its router first
const server = jsonServer.create()
const router = jsonServer.router(db)
// then pass it to json-server-reset
server.use(setApp(server, router.db))
server.use(bodyParser)
server.use(reset)
// the rest of middlewares
server.use(jsonServer.defaults())
server.use(router)
