A build tool for NPM monorepos

Bilt is a CLI that builds, tests, and publishes packages in your monorepos, and does that in the proper order, according to the packages dependency graph, while guaranteeing that only those packages that were not built (and their dependents) get built.

(To go directly to the meat of Bilt, read Structure of a Bilt monorepo and then go to the Getting Started chapter.)

Monorepos are a wonderful concept! They enable us to structure our code as a large set of loosely-coupled packages, instead of one big monolithic codebase, which is usually tightly-coupled.

But the current build tools we have for monorepos are lacking. They are either difficult to work with (Bazel), not powerful enough for big monorepos (Lerna), or can work only with specific codebases (Nx). For more, see the Alternatives section.

Bilt is designed for small and large repos, and is simple to use, assuming your monorepo is built as a series of NPM packages linked together by an NPM dependency graph.
