Running the API

Development

To start the application in development mode, run:

npm install -g nodemon
npm install -g ts-node
npm install -g typescript
npm install

Start the application in dev env:

nodemon

Start the application in production env:

Install ts pm2 and typescript compiler:

npm install -g pm2
pm2 install typescript

example start with scale on 2 core:

pm2 start ./src/index.ts -i 2 --no-daemon

Express server listening on http://localhost:3000/, in development mode The developer mode will watch your changes then will transpile the TypeScript code and re-run the node application automatically.

Testing

To run integration tests:

npm test

Set up environment

In root folder you can find .env. You can use this config or change it for your purposes. If you want to add some new variables, you also need to add them to interface and config object (Look src/config/index.ts)

Usage as OAuth2.0 Server

To use this generator as OAuth2.0 server you should implement client side, that will be handle your redirectUris and make requests to /auth/token/ route. Read more about OAuth2.0

Swagger

npm install -g swagger-jsdoc
swagger-jsdoc -d swaggerDef.js ./src/**/*.ts -o swagger.json

Swagger documentation will be available on route:

http://localhost:3000/docs
