eslint-plugin-call-func

This is a rule to encourage the use of specific func.

Rule Details

✓ GOOD:: function called in outer function

function outer() {
  checkPermissions() // <-- This rule checks if this function is called.
  someFunc()
}

✓ GOOD:: function called with variable assignment

const runFunctionWithCheckPermission = (fn: () => void) => {
  checkPermissions()
  fn()
}

// ref: https://remix.run/docs/en/main/route/loader
export const loader = runFunctionWithCheckPermission(() => { // <-- This rule also can checks if specific wrapper func is used.
  console.log('function called after check permission')
})

✗ BAD: No function called

function outer() {
  someFunc()
}

NOTE

This is useful when you want to run simple code within a framework that exports functions with specific names.

// Using this rule, you can ensure that permission checks are performed within the loader.
// It can be used to supplement parts not supported by the framework.
// related ref: https://github.com/remix-run/remix/discussions/1432
export const loader = () => {
  checkPermissions()
}

// Or you can use a wrapper function to ensure that the permission check is performed.
export const loader = runFunctionWithCheckPermission(() => {
  console.log('function called after check permission')
})
