Json-server installation and use of

• First, tell us about what is json-server, what use is actually very simple:
  JSON-Server is a Node module, run the Express server, you can specify a json api file as a data source.
• Next we need a global json-server installed on the computer:
  

  npm install -g json-server

• Create a new folder, initialization json-server data, and then enter into the folder on the line all the way round :()
  

  nPM heat

• Json-server installation in the initialization of the project:
  

  npm install json-server --save

• Then we in the new folder you will see a package.json file, and there is "json-server": "^ 0.15.1" words, and then create a db.json file in the current directory, under the present document write your own json data: for example, my data:
  

  {
      "users":[
          {
              "name":"Henry",
              "phone":"333-444-555",
              "email":"[email protected]",
              "id":1,
              "age":33,
              "companyId":1
          },{
              "name":"Bucky",
              "phone":"333-444-555",
              "email":"[email protected]",
              "id":2,
              "age":34,
              "companyId":2
          },{
              "name":"Emily",
              "phone":"333-444-555",
              "email":"[email protected]",
              "id":3,
              "age":43,
              "companyId":3
          }
      ],"companies":[
              {
                  "id":1,
                  "name":"Apple",
                  "description":"Apple is good"
              },{
                  "id":2,
                  "name":"Miciosoft",
                  "description":"Miciosoft is good"
              },{
                  "id":3,
                  "name":"Google",
                  "description":"Google is good"
              }
          ]
  }

• Then we can run our local json server:
  

  json-server --watch db.json

  In fact, we can modify the data inside package.json changes run the command:
  
  

  {
    "name": "jsonserver",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": {
      "json:server": "json-server --watch db.json",
      "json:server:remote":"json-server http://jsonplaceholder.typicode.com/db"
    },
    "author": "",
    "license": "ISC",
    "dependencies": {
      "json-server": "^0.15.1"
    }
  }

  After this modification, we only need to enter the command line:
  
  run locally:

  npm run json:server

  Remote mode:

  npm run json:server:remote
