Contributing to an Open Source Project on Github
In this lab you will contribute a fix to an open source project on Github. Successfully completing this lab will require you to have first worked through, and understood, this week's git walkthroughs. If you have not already done so, please setup git and Github as described in the following:
1. Install node.js
We will be contributing to projects that use node.js, its package manager npm, and the npmjs module registry. In order to complete this lab, you will need to install node.js, which you can download here.
2. Understanding package.json
Node uses a special file named package.json to specify metadata about a module. You can read a complete description of package.json at https://docs.npmjs.com/files/package.json.
Let's look at some examples from popular node.js open source projects:
- https://github.com/foreverjs/forever/blob/master/package.json
- https://github.com/expressjs/express/blob/master/package.json
- https://github.com/request/request/blob/master/package.json
- https://github.com/tj/commander.js/blob/master/package.json
These package.json files have common elements, such as:
- a name
- a description
- a version
- a license
There are also some optional fields you can include, for example:
- a list of keywords
- a homepage URL
- repository info
- bugs info
The metadata in package.json is used by the command-line tool npm as well as by the online registry https://www.npmjs.com/. Providing good data for these tools makes it easier for developers to find and use node modules.

Submission
You will have completed your lab when you have done the following:
- Create a Pull Request to a project fixing some problem or omission in their
package.jsonfile - Write a blog post about the process you took to complete this Pull Request, and about what happened next. Was it accepted? How long did it take? What did they say?
- Write about your feelings contributing to your first open source project. What went well? What was hard? What surprised you?
You should complete Lab 2 before the start of week 3.
