📚 General info

  • Very simple backend using node with express and multer to load image files.
  • Client frontend uses Ionic-Angular or Ionic-React to show user controls to upload file from PC file system.

📶 Technologies

Frontends:

Backend:

  • cors Cross Origin Resource Sharing Connect/Express middleware
  • Express v4 Node.js middleware, includes body parsing
  • Morgan v1 HTTP request logger middleware for node.js
  • Multer v1 Middleware for handling multipart/form-data.
  • Busboy used by Multer as a streaming parser for HTML form data for node.js

💾 Setup

/Ionic-Angular & /Ionic-React Frontends:

  • cd client-angular then npm i to install Angular frontend dependencies
  • cd client-react then npm i to install React frontend dependencies
  • I had to have a Google Chrome CORS extension activated for this to work
  • Angular frontend: Run ionic serve & navigate to http://localhost:8080/ or ng serve & navigate to http://localhost:4200/ to run server. The app will automatically reload if you change any of the source files.
  • React frontend: Run npm run start & navigate to http://localhost:3001/
  • The apps will automatically reload if you change any of the source files.

/server-express Backend:

  • cd server-express then npm i to install backend dependencies
  • Run node index.js for a node.js server. Backend does not update automatically as nodemon not used

💻 Code Examples

  • Extract from server-express/index.js to show use of dependencies and posting of objects to uploads folder.
app.use(cors());
app.use(morgan("combined"));
app.use(express.json());
app.use(express.urlencoded({ extended: true }));

app.post("/upload", upload.single("photo"), (req, res) => {
  console.log(req.file);
});

app.post("/uploads", upload.array("photos[]"), (req, res) => {
  console.log(req.files);
});

🆒 Features

  • Tutorial shows different front-ends that can be used to pass objects to the backend
  • Backend 'uploads' folder is automically created if it does not exist already.

📋 Status & To-Do List

  • Status: Working
  • To-Do: Nothing. There is repeated frontend ionic-angular code and scope for refactoring - I am leaving it as is for now.
