Dyte Backend Task

Dyte's take home task for backend development.

Info

• Uses Express as backend.
• Runs Moleculer API Gateway in middleware mode on express. [Link]
• Uses Prisma as the Database ORM with Postgres as the database.
• Has two Moleculer services: API Gateway and Webhooks.
• Batch size for concurrent requests [trigger route] can be configured by env variables
• In addition to JWTs, admins have to send admin-id as a header, which is cross-checked with the enviroment variable (can be a set of rotating uuids which is shared internally)
• Written in TypeScript. (obv)
• Postman Collection(JSON) here

Instructions To Run

• Install dependencies

npm install

• Run Postgres (remember to set env vars!)
• Perform DB migrations with prisma

npx prisma migrate dev
npx prisma generate

• Start the server (also transpiles TS to dist/)

npm start

NPM scripts

• npm run build: Transpiles TS to JS
• npm run start: starts the moleculer and express servers
• npm run cli: Start a CLI and connect to production. Don't forget to set production namespace with --ns argument in script
• npm run dc:up: Start the stack with Docker Compose
• npm run dc:down: Stop the stack with Docker Compose

TODOs:

• test retry logic properly (I'm sure interceptor method is wrong)
• dockerize
