Using Typescript Types with JSDoc

Experimentation repo for various ways to type react apps.

See ./src folder for examples

Globally enable TS checking

To enable TS to run everywhere use the js/ts.implicitProjectConfig.checkJS setting in your VScode workspace or user settings.

"js/ts.implicitProjectConfig.checkJs": true

Typescript ignore errors

Pro-tip: CLI tool to automatically add ignore comments

The //@ts-ignore tells TypeScript to ignore the TypeScript errors in the line following the comment.

function mapValues(object, mapFunction) {
  // @ts-ignore
  return Object.fromEntries(Object.entries(object).map(([key, value]) => [key, mapFunction(value)]))
}

This //@ts-expect-error will ignore any typechecking failures in the next line, but will fail the typecheck if there are no errors

function mapValues(object, mapFunction) {
  //@ts-expect-error
  return Object.fromEntries(Object.entries(object).map(([key, value]) => [key, mapFunction(value)]))
}

Ignoring multiple lines

// @ts-ignore-start
// @ts-ignore-end

Nuclear option to disable in file

// @ts-nocheck
