Create a set of API endpoints and introduce some development best practices. Before deploying to Heroku, learn how all the pieces work together when you create a small project using continuous integration and test-driven development. We will use a test-driven development (TDD) approach and set up continuous integration (CI) jobs to automatically run our tests and provide code quality and coverage reports. We will study controllers, models (using PostgreSQL), [b][url=https://zh-cn.awbdirectory.com/]WhatsApp database[/url][/b]  error handling and asynchronous Express middleware. Finally, we'll complete the CI/CD pipeline by configuring automated deployment on Heroku. It sounds like a lot, but this tutorial is aimed at beginners who are ready to try a backend project of some complexity and may still be confused about how all the pieces fit together in a real project.

It's powerful without being overwhelming, and is broken into sections you can complete in a reasonable amount of time. Getting started # The first step is to create a new directory for your project and start a new node project. Node is required to continue this tutorial.

# create a new directory mkdir express-api-template # change to the newly-created directory cd express-api-template # initialize a new Node.js project npm init Copy and answer the following questions to generate the package.json file. This file contains information about your project. Examples of such information include the dependencies it uses, the command to start the project, etc. You can now open the project folder in the editor of your choice. I use visual studio code.
