What is the purpose of running tsc --build without any project references?

Out of curiosity, I decided to experiment by executing tsc --build on a project without any project references. Surprisingly, the command ran smoothly and completed without any issues. I expected there to be a warning or error since the build flag is typically associated with project references.

This experience led me to wonder: what distinguishes running tsc from running tsc --build in a project that doesn't utilize project references?

Answer №1

If your tsconfig.json file does not have any project references, then in your use-case, both tsc and tsc --build are essentially the same.

However, as your project expands and you need to effectively manage dependencies and build order across multiple projects (often seen in monorepos), using tsc --build becomes more beneficial.
