Article on the time it takes to run type-checking in large-scale ⌨️ TypeScript projects.
- The TypeScript compiler is single-threaded
- Bazel build files and TSConfig files are auto-generated using Gazelle to declare dependencies automatically (and remove unnecessary dependencies)
- Tooling on top of the build system to get a better understanding of the system as a whole
- Using measurements to focus efforts on the longest dependency chains
- Isolated declarations speed up the process because projects need to only type-check the declarations of their dependencies. Requires explicitly defining types that could otherwise be automatically inferred. This can already be automatically inferred, automated tooling, such as ts-fix, can take care of this instead of updating the code manually.
