Hosted Projects

The OpenJS Foundation hosts some of the most important projects in the JavaScript ecosystem.  As a neutral non-profit organization, our goal is to provide a home where projects can build and support a sustainable community of diverse contributors.

We strongly believe in sharing best practices and reducing redundant administrative work across projects, particularly when it comes to non-technical governance.  To that end we have the Cross Project Council, or CPC, to centralize coordination among projects as well as certain technical governance and moderation processes.  One of the CPC’s primary functions will be to oversee the progression of projects between stages of their lifecycles.

Projects hosted by the OpenJS Foundation fall into one of four categories:

  • Impact stage is generally for large, mature projects.
  • At-Large stage is for new projects, stable projects with minimal needs, and everything in between.
  • Incubation stage is for projects which are in the process of joining the OpenJS Foundation.
  • Emeritus stage is for projects which 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.

The project lifecycle is documented in the Project Progression proposal.

Impact Projects

Impact projects are on a sustaining cycle of development, maintenance, and long-term support. These projects are used commonly in enterprise production environments and have large, well-established project communities.

Impact projects are expected to participate actively in Cross Project Council proceedings, and as such have a binding vote on CPC matters requiring a formal vote, such as the election of a CPC Director. They receive ongoing financial and marketing support from the Foundation, and are expected to cross-promote the foundation along with their activities.

At-Large Projects

At-Large projects are those which the CPC believes are, or have the potential to be, important to Impact projects in particular or the ecosystem in general. They may be early-stage projects just getting started, or they may be long-established projects with minimal resource needs.

The OpenJS Foundation provides a beneficial, neutral home for these projects in order to foster collaborative development and provide a path to deeper alignment with other Foundation projects.

Incubation Projects

Incubating projects are projects that are in the process of completing their on-boarding checklist to join the foundation. Projects in this phase may be looking to join the foundation as At-Large or Impact Stage. Members of incubating projects are invited to join Cross Project Council meetings as a guest, please refer to the CPC Charter for details on how guests may participate in the meetings.

Emeritus Projects

Emeritus projects are those which the maintainers feel have reached or are nearing end-of-life. Emeritus projects have contributed to the ecosystem, but are not necessarily recommended for modern development as there may be more actively maintained choices.

The Foundation appreciates the contributions of these projects and their communities, and the role they have played in moving the ecosystem forward.
