Node.js PostgreSQL CRUD example with Express Rest APIs
Full Article with implementation:
We will build Rest Apis that can create, retrieve, update, delete and find Tutorials by title.
The following table shows overview of the Rest APIs that will be exported:
api/tutorials get all Tutorialsapi/tutorials/:id get Tutorial by idapi/tutorials add new Tutorialapi/tutorials/:id update Tutorial by idapi/tutorials/:id remove Tutorial by idapi/tutorials remove all Tutorialsapi/tutorials/published find all published Tutorialsapi/tutorials?title=[kw] find all Tutorials which title contains 'kw'Front-end that works well with this Back-end
Angular 8 / Angular 10 / Angular 11 / Angular 12 / Angular 13 / Angular 14 / Angular 15 / Angular 16
This is our Node.js PostgreSQL CRUD example using Express & Sequelize application demo, test Rest Apis with Postman.
Run our Node.js application with command: node server.js.
Using Postman, we're gonna test all the Apis above.
POST /tutorials ApiAfter creating some new Tutorials, you can check PostgreSQL table:
