Ways to display all utilized typescript types within a project

Here is a snippet of code I'm working with in my project:

describe('Feature active', () => {
  it('Should render a Feature', () => {
    const wrapper = shallow(<MyComponent prop1={1}/>);
    expect(wrapper.prop('prop1')).to.equal(1);
  });
});

When it comes to typescript, I've encountered some issues resolving the type of describe and it. By including @types/jest in my tsconfig.json file under types: [ '@types/jest' ], I was able to fix these clashes between jest and mocha.

Now, I'm curious about how compilerOption.types function in more detail. Specifically, I'd like to know all the packages (similar to @types/jest) that typescript actively uses in my project.

Although I have several @types/... packages listed in my package.json, my tsc command seems to work fine with just types: [ '@types/jest' ]. Does this mean that tsc isn't utilizing the other types?

Is there a way or specific command that can provide me with a list of all the types the tsc compiler is employing to transpile my code?

Answer №1

When a module is imported and the declaration of node_modules/@types is specified in the typeRoots section, other @types/... packages are utilized (typically implicit by default).

The inclusion of jest in the types makes its functionalities globally accessible, eliminating the need to individually import helper methods like describe or it.
