Node.js, Express and MongodB: Create a Restfull API with images upload
What will you learn by downloading my code?
- Use of express to make API creation simple
- Using mongoose to manage communication with Mongo DB
- Image Upload with multer
- Image deletion with the notions of paths and file system in node
- Field validation using express-validator
- Creation of reusable methods thanks to the concept of modules
- Creation of a functional REST API with Node.js, Express and Mongo DB.
Are you ready ? Let's go
Clone the repository then run npm install
You can install mongodb locally or use Mongo Atlas (online). In both cases, go to the app.js file then replace the url mongodb://localhost:27017/player-db with your url. In my case I use Mongo DB locally. It is therefore available on port 27017(by default) and the name of my database is player-db.
To launch your project, just type the following command : node app.js. Your API will therefore run on port 3000
This is an API that manages players (football for example). A player is characterized by:
- name: the name of the player
- age: the player's age
- bio: a brief biography of the player (at least 15 characters)
- photoUrl: player photo
- createdAt and updatedAt are generated automatically using the timestamps: true statement in the models/player.js file
So we have a total of 5 routes
- Add player http://localhost:3000/api/v1/player
- List of all players http://localhost:3000/api/v1/players
- Find player by Id http://localhost:3000/api/v1/player/:playerId
- Update player http://localhost:3000/api/v1/player/:playerId
- Delete player http://localhost:3000/api/v1/player/:playerId
- When you add a player their photo is placed in the /images folder (make sure to create this folder at the same level as the controllers folder if it doesn't exist).
- I delete player image if this image was replaced during the update (or if the player was deleted)
- In the utils/syd-functions.js folder you will find reusable functions in the controllers/player.js
- Add Player
- List of players
