REST API in Node to load and query CSV

This backend project receives CSV files using a RESTful Node API, saves them locally as files and in MongoDB. It also has an endpoint to query the data saved in the database.

• Node.js
• Express.js
• MongoDB
• Mongoose
• Multer
• CsvtoJSON
• Nodemon
• Docker
• Jest
• Supertest
• Dotenv

*** This backend project should be used with the frontend, located at shaw-csv-frontend, however, it is also a standalone RESTful API, which can be used with Postman/Insomnia or other mean that communicates with HTTP REST endpoints ***

• Get the link of the repository: [email protected]:arthurborgesdev/shaw-csv-frontend.git
• Clone it as [email protected]:arthurborgesdev/shaw-csv-frontend.git on a Terminal
• Change directory to it by cd shaw-csv-frontend
• Run npm i on a Terminal

This project can be setup with Docker (preferred way if you don't have MongoDB installed or don't want to install it) or with a locally installed Mongo.

Run docker compose command docker-compose -f docker-compose.yml up

docker ps -> Get container ID

docker logs <container id> -> Print app output

docker exec -it <container id> /bin/bash -> Get into the container

docker kill <container id> -> Shutdown the container

• Install MongoDB according to your OS instructions if you don't have it installed
• Run it accordingly to your OS instructions
• Enter in the mongo shell by typing mongosh on a Terminal
• Create a root user with pass password (Step necessary to match the config for Docker and Nodejs env variable):

  use admin
  db.createUser(
  ... {
  ... user: "root",
  ... pwd:  "pass",
  ... roles: [ { role: "root", db: "admin" }]
  ... }
  ... )

npm run dev will run nodemon for local testing

npm run test:unit

npm run test:integration

npm run test
