Setting up Travis CI for Node.js

1. Introduction

Travis CI is a continuous integration service that helps automate the testing and deployment of your Node.js applications. In this lesson, we will walk through the setup process for integrating Travis CI with a Node.js project.

2. Prerequisites

3. Setting Up Travis CI

1. Visit the Travis CI website.
2. Sign in with your GitHub account.
3. Authorize Travis CI to access your GitHub repositories.
4. Enable Travis CI for your specific repository.

4. Configuring .travis.yml

Once Travis CI is set up, you need to create a configuration file named `.travis.yml` in the root of your Node.js project. This file tells Travis how to build and test your application.

.travis.yml
language: node_js
node_js:
  - "14"
  - "16"
  - "18"
script:
  - npm install
  - npm test
            

In the above configuration:

• language: Specifies the programming language.
• node_js: Lists the Node.js versions to test against.
• script: Contains the commands to run for testing.

5. Best Practices

• Use environment variables to manage sensitive data.
• Keep your `.travis.yml` file organized and well-commented.
• Run tests in parallel when possible to speed up the CI process.
