This is an advanced demo of the best practices of using pg-promise, and managing your database architecture.
It shows how to organize an enterprise-level database application, with consideration for ever-growing complexity of the database and queries.
The demo focuses on the following:
- The best way to organize your database module
- Use of the Repository pattern for your database
- Efficient use of queries via external SQL files
- Query monitoring and error diagnostics
The demo includes two separate implementations, with identical functionality:
Installing & Running
You can either clone it or install via
$ npm install pg-promise-demo.
This demo is here mostly for you to browse through its source code, understand its structure and the overall approach. It is also simple enough that running it isn't really necessary.
Once the application is up and running, you can fire away URL commands in a browser, as per the web API that's implemented, while watching what's happening in:
- the console output (make sure you have NODE_ENV=
- errors log - file
The application implements two tables:
users->products as one-to-many. Once the app is running, you should create
and populate those as the very first commands:
/users/create /users/init /products/create
After that see other supported API commands in the code:
/users/empty /users/drop /users/find/:id /users/remove/:id /users/all /users/total /products/drop /products/empty /products/add/:userId/:name /products/find/:userId/:name /products/remove/:id /products/all /products/total
