New Packages
bcryptjs: This npm package can be used to hash passwords before storing them in the database.- @redux/toolkit, react-redux and redux-persist : Set of libraries to manage and persist application state.
Backend
- If you
export defualt something from a js file, then while importing that thing you can name it anything.
Exporting file: auth.route.js
export default router
Importing file: index.js
import authRoutes from './routes/auth.route.js'
Notice how router is imported by the name authRoutes.
- However, if you just
export something from a js file, then while importing that thing you need to use the same name.
Exporting file: auth.controller.js
export const signup = async ()
Importing file: auth.route.js
import { signup } from '../controllers/auth.controller.js'
- In a POST request if you are sending JSON data as the request body then you need to specify this statement
app.use(express.json()) so that the JSON data reaches your middleware functions.
- The default form behavior is that whenever submit is hit, the form would get refreshed, in order to prevent this default behavior we can use:
const handleSubmit = async (e) => e.preventDefault()
- You can use the
onChange event handler on text inputs to detect change in real time and perform validation.
Frontend
- When using
redux-persist, you might encounter issues with the serializability check middleware because redux-persist can store non-serializable values (like promises) in the state. To avoid these issues, you can disable the serializability check middleware.
