Welcome to Free Code Camp's open source codebase and curriculum!

Free Code Camp is a friendly open-source community where you learn to code and help nonprofits.

We help our campers build job-worthy portfolios of real apps used by real people, while helping nonprofits.

You start by working through our self-paced, browser-based full stack JavaScript curriculum.

By working through our curriculum, you can earn four certifications:

1. Front End Certification

The first section will teach you the basics of how webpages work and also introduce you to JavaScript programming.

Skills you'll practice include HTML, CSS, JavaScript, jQuery and Bootstrap.

To earn this certification, you'll build 10 front-end projects and implement many JavaScript algorithms.

2. Data Visualization Certification

The second section builds upon the first and introduces you to more advanced topics such as Sass, React and D3.

To earn this certification, you'll build 5 React-apps and 5 Data visualization apps using D3.js.

3. Back End Certification

The third section introduces you to back end development using Node.js, Express, and MongoDB. It also teaches you about the important concept of source control using Git.

To earn this certification, you'll build 5 APIs and 5 full stack apps.

We will accept solutions implemented in any programming language, as long as both a live demo and the source code are publicly accessible.

4. Full Stack Certification

The fourth section is where you'll get real-world experience by working on projects for nonprofits. We'll pair you with another camper, an agile project manager, and a stakeholder from a nonprofit organization. Together, you'll plan, build and maintain apps that help that nonprofit carry out its mission more effectively.

For this certification, you'll work on two projects from scratch and then maintain/upgrade two existing projects.


This code is running live at FreeCodeCamp.com. We also have Gitter chat room, a Medium publication, and even a YouTube channel.
