Compiler option |
The compiler
option allows you to define the compiler to be used. It'll be used to load the NodeJS module holding the TypeScript compiler.
The default value is typescript
, which will load the original TypeScript compiler module.
The loaded version will depend on the one installed in your project.
If you use a custom compiler, such as ttypescript
, make sure its API is the same as the original TypeScript, at least for what ts-jest
is using.
