Overview

We create 2 projects: {Node.js, Angular}

Node.js RestAPIs

Project structure ->

angular-6-http-client-upload-files-to-nodejs-rest-api-sequelize-mysql + nodejs-project-structure

– Node.js project exposes RestAPIs to upload/download files:

  • router.post(‘/api/file/upload’, upload.single(“file”), fileWorker.uploadFile);
  • router.get(‘/api/file/all’, fileWorker.listAllFiles);
  • router.get(‘/api/file/:id’, fileWorker.downloadFile);

Configure cross-origin for Angular-Client which running at port: 4200.


const cors = require('cors')
const corsOptions = {
  origin: 'http://localhost:4200',
  optionsSuccessStatus: 200
}
app.use(cors(corsOptions))
