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
