The creator of popular open source projects like React, React-Native and Jest, joins the OpenJS Foundation

SAN FRANCISCO – May 10, 2023 – The OpenJS Foundation, providing vendor-neutral support for sustained growth within the open source JavaScript community, is announcing today that Meta has joined as a gold member.

“Welcome Meta! Their positive effect on the JavaScript ecosystem has been amazing. Heavy users at scale of JavaScript itself, creators of React and React-Native, creators of multiple key open source projects,” said Robin Ginn, OpenJS Foundation Executive Director. “We look forward to working more with Meta’s leadership and expertise to increase support for the diverse open source communities at OpenJS.”

Meta Open Source has been key in creating and open sourcing many projects crucial to the JavaScript ecosystem, such as React, Jest, and Flow. Last year, Meta contributed its popular JavaScript testing project Jest to OpenJS, which garnered an enthusiastic response from developers for this community-led project.

As a global leader with a mission of creating community and bringing people closer together, Meta understands the importance of open collaboration to sustain and improve JavaScript development. Working collectively with other member companies and with the guidance of the OpenJS Foundation, Meta will continue to contribute and advocate in the community.

“Open source has the potential to be more inclusive and more empowering than ever. Joining the OpenJS Foundation is a large step forward in supporting our open source communities. We hope to provide not only leadership, but to learn from the community,” said Killian Murphy, Sr. Engineering Director, Developer Experience & Platforms.

“The broader JavaScript ecosystem benefits from Meta becoming an OpenJS Foundation member. In fact, we’ve already been working together in multiple different ways, and this makes official what has already been a great relationship,” said Shayne Boyer, OpenJS Foundation Board Director. “

Jest Project Moves to OpenJS Foundation with Meta Open Source Contribution

By OpenJS Foundation Announcement, Blog, Jest

The OpenJS Foundation is announcing that popular JavaScript testing framework Jest is joining as an Impact Project! Jest and its assets are being donated proudly by Meta Open Source.

Jest is a JavaScript testing framework. It allows you to write tests with an API with little configuration. As the Jest team likes to say, Jest makes testing “delightful.”

Jest currently has over 17 million weekly downloads and 38,000+ GitHub stars, making it the most used testing framework in the JavaScript ecosystem. It consistently ranks as one of the JavaScript libraries with the highest satisfaction, and is used by companies of all sizes including Amazon, Google, Meta, Microsoft, and Stripe. Jest 28 was just released.

“We are excited to welcome Jest into the OpenJS Foundation. Building a community requires dedicated people and great technology, which Jest has been doing since 2011. Jest is used commonly in enterprise production environments and open source projects and will benefit from a reliable structure for open governance and legal support,” said Robin Ginn, OpenJS Foundation executive director. “As the vendor-neutral home to almost 40 open source projects, Jest already fits in well with our ecosystem of projects. We look forward to providing resources and support to Jest to help their community to grow.”

“Jest has been working to follow the OpenJS Foundation principles around operating transparently, openly, and collaboratively. Joining the OpenJS Foundation allows our team to make greater investments to grow contributors and impact,” said Rick Hanlon, Front End Engineer on React Core at Meta and Jest Core Contributor. “This is a big step forward for Jest. I want to thank the sponsors and contributors who have helped get us this far and who will continue to play an important role in Jest’s next stage.”

“We have been a community-led project for quite some time. We believe in community-led development, and continually strengthening our community, and joining the OpenJS Foundation will help us strengthen and broaden our community,” said Simen Bekkhus, developer at Folio and Jest lead maintainer. “I see this as a very positive change and a way for the Jest community to flourish.”

“Big thanks to Meta Open Source. JavaScript developers worldwide will benefit from having Jest be part of the OpenJS Foundation. This move strengthens the JavaScript ecosystem and will help the Jest developer community to continue to grow,” said Joe Sepi, OpenJS Foundation Cross Project Council chairperson and Open Tech Program Director at IBM. “Congratulations to the whole Jest team and community.”

“By moving to the OpenJS Foundation, we are becoming more open and welcoming to first-time community members and contributors. Open governance is key to the next step in our evolution as a community,” said Christian Bromann, OpenJS Foundation Cross Project Council Member representing the WebdriverIO project and Founding Engineer, Stateful, Inc. “I personally have learned you can earn a living by following your passion in life. We are making Jest a more inclusive community because we believe this is the best way to build a strong, vibrant community that will allow you to follow your passion.”

Just like all OpenJS projects, Jest is entering the foundation as an incubating project while they complete the on-boarding checklist process. Projects in this phase can be designated as an At-Large or Impact Stage project.

There are four different types of projects hosted by the OpenJS Foundation: Impact projects are generally large, mature projects. At-Large projects are new, stable projects with minimal needs. Incubation projects are in the process of joining the OpenJS Foundation. And Emeritus projects have completed their lifecycle and are retired. In addition, the CPC oversees an Incubation process for projects which seek to be hosted by the OpenJS Foundation.
