A project that strives to develop high-quality, community contributed Solid primitives. All utilities are well tested and continuously maintained. Every contribution to the repository is checked for quality and maintained to the highest degree of excellence. The ultimate goal is to extend Solid's primary and secondary primitives with a set of tertiary primitives.

While Solid Primitives is not officially maintained by the SolidJS Core Team, it is managed by members of the SolidJS core and ecosystem teams. This separation allows the core library to iterate independently while allowing Solid Primitives to remain in-sync with future plans.

The goal of Solid Primitives is to wrap client and server side functionality to provide a fully reactive API layer. Ultimately the more rooted our tertiary primitives are, the more they act as foundation within Solid's base ecosystem. With well built and re-used foundations, the smaller (aggregate tree-shaking benefits), more concise (readability) and stable (consistent and managed testing + maintenance) applications can be overall.
