Project structuring is an important topic because the way you bootstrap your application can determine the whole development experience throughout the life of the project.
Where we define endpoints should be noun based and do not use verbs.
router.get("api/v1/get-book-list", getBookMethod); // avoid router.get("api/v1/book-list", getBookMethod); // please use
Basic skeleton of the API should be there if the method is getting big, use a service file and move some logic there. Write reusable code and common functions.
Ex. You can’t save a web socket circular object into an app instance of express.
Tests are not just for checking whether a module produces the expected output, they also document your modules. Because of this, it is easier to understand if test files are placed next to the implementation.
Put your additional test files in a separate test folder to avoid confusion.
To place your configuration files, use a config directory.
Avoid writing long scripts in package.json. Create a separate file for that and use that file.
Third-party API integration in separate service files and maintain them in the services folder.
To sign and verify a token create a separate jwt-service and import this to sign and verify the token.
Create a subfolder on the basis of type like server-utilities-
Let’s assume we are dealing with Postgres, then-
Add an express-validator to validate and sanitize the request. Validation should be added on the model level and on the request level.
Only server-related essential credentials should be there for third parties etc.
Create a separate file and read from there like environment.json or put them in constants.js in utilities.
"doc": "apidoc -i app/ -o client/dist/eps-client/doc", and npm run doc apidoc.json will be in parallel of package.json
