For the last five years, Mozilla has participated in the Outreachy<\/a> program to provide three-month internships for people from groups traditionally underrepresented in tech. From December 2017 – March 2018, interns Ravneet Kaur<\/a> and Natalia Milavanova<\/a> worked under the guidance of Christopher Grebs<\/a> and Luca Greco<\/a> to improve the add-ons linter.<\/p>\n

The add-ons linter<\/a> is a tool that warns of potential problems within an extension\u2019s code. Developers can use the web-ext command line tool<\/a> to run the linter locally to check for potential issues during development, and addons.mozilla.org<\/a> (AMO) uses it to validate an extension during the submission process.<\/p>\n

Ravneet\u2019s internship project was to land a localization feature to the add-ons linter. By offering the option to see errors and warnings in multiple languages, the linter can be more accessible to add-on developers who prefer to work with non-English languages. Ravneet successfully adapted Pontoon\u2019s<\/a> localization method for the add-ons linter and extracted about 19,000 lines of code in the process.<\/p>\n

Outreachy internships are a great way to gain real-world experience working with distributed teams and grow software development skills. \u201cThis project was the first time I was introduced to the idea of bundling code using technologies like webpack<\/a>,\u201d Ravneet says. \u201cAfter going through its documentation and reading blog posts about it, I was fascinated about the idea of bundling code together and building small, minimalistic projects in production, while having a wide variety of maintainable files and folders in the project\u2019s source.\u201d<\/p>\n

Natalia tackled a different challenge: improve the linter\u2019s validation by rewriting a large chunk of the code and test suite into async functions. For a long time, the linter\u2019s code had been cumbersome to work with. After refactoring the code, Natalia removed approximately 3% of the code. Luca notes, \u201cThanks to Natalia\u2019s hard work on this this project, our ability to debug and handle errors in the add-ons linter has been greatly improved. It\u2019s now easier to read and understand the sources, and prepare for the changes that are coming next.\u201d<\/p>\n

Thank you for all of your contributions, Natalia and Ravneet! We look forward to seeing your future accomplishments.<\/p>\n
