How quickly and easily run a local server with fake api data (mocks)?

Sometimes you need to develop a frontend part of a project without a ready-made api, knowing only its structure. In this case, using json-schema-faker, you can generate fake data (mocks) and deploy it to your local server.

Firstly u will need to install json-schema-faker package

 yarn add json-schema-faker 

Then open the package.json file and add scripts with the following

 // ... "scripts": { // ... "start-mockapi": "json-server --watch ./mocks/api/db.json --port 3001", "generate-mock-data": "node ./generateMockData", } 

After installation, you will need to describe the structure in ./mocks/dataSchema.js of future mocks. You can find more information here.

 const schema = { reports: { type: 'array', minItems: 5, maxItems: 10, items: { id: { type: 'integer', unique: true, minimum: 1, maximum: 1000, }, title: { enum: ['production', 'azure data', 'azure data 2'], }, logo: 'https://picsum.photos/200' }, }, } module.exports = schema; 

Copy paste script for generating mock data from here in ./generateMockData.js and run the following

 yarn generate-mock-data && yarn start-mockapi
