Node.js RestAPIs
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))
