Json-server + Fake API

Key Points

  • Do npm init
    • Generate the package.json
  • Install  faker from below link
  • “filldata”: “node app.js > db.json“
    • node app.js will generte the employees array
    • export const Users = {
        employees: [],
      };
  •  console.log(JSON.stringify(Users));
    • This will generate {
      “employees”:
      [
          { “id”: ” ….},
          { “id”: ” ….},
      ]

      }

  • Now all we need to do is to push to db.json
    • “filldata”: “node app.js > db.json”,
    • This is written in package.json
    • This will push data to db.json from above generated employees object
    • db.json works only on object. So make sure you dont do any mistake of keeping array in db.json
      • That is the reason if you see users is object , that has employees which we populated
        export const Users = {
          employees: [],
        };
  • “populateAndLoad“: “npm run filldata &&  json-server –watch db.json“
    • npm run filldata :- This will do the filldata – which pushes data from app.js to db.json
    • json-server –watch db.json :-  This will run the json-server at default port 3000
    • But you can specifially run at specific port
      • json-server –watch db.json –port 3004
         
  • Do npm run populateAndLoad to load the db.json and start loading the data
  • Use postman to put, post, delete , get. This will update the db.json.

export const Users = {

};

export function createRandomUser() {
  return {
    id: faker.datatype.uuid(),
    employeeName: faker.internet.userName(),
    employeeEmail: faker.internet.email(),
    empDob: faker.date.birthdate(),
  };
}

Array.from({ length: 10 }).forEach(() => {
  Users.employees.push(createRandomUser());
});

console.log(JSON.stringify(Users));
