finse

Find which files reference the target file

Features

• Friendly output
• Supports alias via tsconfig.json
• Supports esm and cjs
• Detect the project root directory
• Unlimited file types

Install

$ npm i -g finse
$ finse -h # help

Usage

Suppose we have a project, its directory structure is like this：

finse
  └─ test
      └─ demo
          ├─ bar
              ├─ corge
                  └─ nacho.vue
              └─ oop.ts
          ├─ foo
              └─ sharp.js # sdf
          └─ thud.tsx

And you want to find out which files reference oop.ts，just run：

$ finse test/demo/bar/oop.ts

Maybe you will see the output similar to this:

The yellow background represents the file you want to match, the cyan background is the file that "uses" it

API

--root [rootname]

• Specify the project root directory

--expand

• Expand collapsed file tree

--link

• Display the absolute path of the file. That way other files can be accessed directly through the terminal

--ignore

• Ignore file does not exist errors

Motivation

• It's hard to find which other files use the target file

• Search in IDEA is not enough, it's difficult to give exact search keywords

How is works ?

• First, it will detect the project root directory if no directory is specified
• By default, the directory where package.json is located is selected as the root directory
• Next, all reasonable files in the directory will be scanned
• Then match the contents of the file to see if there is an import statement
• finse will recognize the following imports

// static import
import xx from 'xxx'

if (Math.random() > 0.5) {
  // dynamic import
  import('xx.ts')
}

// require import
require('./xx/xx')

finse works with regular expressions, But don't worry about "accidental recognition":

// Yes, legal import
import xx from 'xxx'

// No，Imports in comments are not recognized
// comment: import xx from 'xxx'

And supports identifying paths with alias:

<script setup>
import xx from '@/xx'
// or:
import xxx from '~/xx'
</script>

But have to make sure there is such a configuration in [t|j]sconfig.json:

{
  "compilerOptions": {
    "paths": {
      "~/*": ["test/demo/bar/*"],
      "@/*": ["src/*"]
    }
  }
}

finse

it's mean find use
