Exploring Travis CI API with JavaScript

Travis CI is one of the most popular continuous integration and delivery platform which helps you to automate your software development workflow. Travis CI offers a public API which allows developers to interact with the platform in many different ways. In this article, we’ll explore how to use the Travis CI API with JavaScript.

Getting Started

Before we start interacting with the Travis CI API, we have to understand the basic concepts of Travis CI. Travis CI uses build jobs to run your tests, build your app, and deploy it if everything went well. A job is a sequence of tasks that should be executed in order.

To use Travis CI API, you need to authenticate yourself. You can authenticate yourself using your Travis CI account credentials.

Authenticating with Travis CI API

Here is an example code on how to authenticate with Travis CI API using JavaScript:

const token = "your_travis_ci_access_token";
const request = require("request");

request({
    method: "GET",
    url: `https://api.travis-ci.com/auth/user?access_token=${token}`,
    headers: {
        "Travis-API-Version": "3"
    }
}, (error, response, body) => {
    if (error) {
        console.log(error);
    } else {
        console.log(body);
    }
});

In the above code snippet, we are using the request module to make a GET request to the Travis CI API /auth/user endpoint. We are passing our access token to authenticate ourselves. If the authentication is successful, the response body will contain the user information.

Using Travis CI API to Get Build Information

Next, let's retrieve a list of builds that have been run recently on Travis CI. Here is an example code on how to do that using JavaScript:

const token = "your_travis_ci_access_token";
const request = require("request");

request({
    method: "GET",
    url: `https://api.travis-ci.com/repo/<owner>%2F<repository>/builds`,
    headers: {
        "Travis-API-Version": "3",
        "Authorization": `token ${token}`
    }
}, (error, response, body) => {
    if (error) {
        console.log(error);
    } else {
        console.log(body);
    }
});

In the above code snippet, we are making a GET request to the /builds endpoint by replacing <owner> and <repository> with your actual values. We are passing our access token for authentication. If the request is successful, the response body will contain an array of build information.

Conclusion

In this post, we’ve explored how to use the Travis CI API with JavaScript. We started by understanding the basic concepts of Travis CI and how to authenticate with the API. Then, we looked at how to use the API to retrieve a list of recent builds. Using the Travis CI API, you can do many things such as creating new builds, canceling existing builds, and so on. It all depends on your needs and how you want to use the platform.
