Overview

JavaScript projects can use a jsconfig.json file instead, which acts almost the same but has some JavaScript-related compiler flags enabled by default.

A project is compiled in one of the following ways:

  • By invoking tsc with no input files, in which case the compiler searches for the file starting in the current directory and continuing up the parent directory chain.
  • By invoking tsc with no input files and a --project (or just -p) command line option that specifies the path of a directory containing a tsconfig.json file, or a path to a valid .json file containing the configurations.

When input files are specified on the command line, tsconfig.json files are ignored.

Examples

  • Using the property

  • Using the "include" and "exclude" properties

Depending on the JavaScript runtime environment which you intend to run your code in, there may be a base configuration which you can use at . These are tsconfig.json files which your project extends from which simplifies your tsconfig.json by handling the runtime support.

This lets your tsconfig.json focus on the unique choices for your project, and not all of the runtime mechanics. There are a few tsconfig bases already, and we’re hoping the community can add more for different environments.

Details

The property can be omitted, in which case the compiler’s defaults are used. See our full list of supported Compiler Options.
