fnclip lets you copy and use only the functions you need, without installing entire libraries or worrying about dependencies.

QUICK START!

npx fnclip add pipe

This will add the pipe function to src/utils/fnclip/pipe.ts (or .js and .d.ts) and update src/utils/fnclip/index.ts to export it.

✨ Features

1. Each single file under src/functions/ represents an independent function without any dependencies, you can copy and use it directly!
2. Provide a convenient cli for quick access (see below).
3. Automatically detects whether you are using JavaScript or TypeScript, but you can specify manually if needed.
4. The cli only support nodejs currently. But you can still just copy the file you want!

🚀 Usage

To check all details, please use --help!

Now have commands add, clear, list.

npx fnclip -h
npx fnclip add -h

Adding functions

npx fnclip add pipe

This will add pipe to src/utils/fnclip/pipe.ts, and automatically add or update src/utils/fnclip/index.ts which contains export * from './pipe.ts'.

You can also use the following aliases: add, i, install.

npx fnclip i objectKeys objectMap nonNullable

This will add multiple functions to your project, which may be useful when you start a new project.

Changing target path

Add a function to a custom directory, for example:

npx fnclip add pipe --cwd packages/other --dir fnclip

About index file

This will prevent adding/updating index file.

npx fnclip add pipe --no-index

Or specify a path of index file

npx fnclip add pipe --index-path ../fnclip.js

It will specify index path in src/utils/fnclip.js instead of src/utils/fnclip/index.js

You can also omit extension and it will automatically add it for you --index-path ../fnclip

Typescript or Javascript

By default it will automatically choose ts or js. Or you can manually specify it:

npx fnclip add pipe --ts
npx fnclip add pipe --no-ts

Pre-configuration

You can use npx fnclip config to add a config file to your project:

<root>/fnclip.config.js

It looks like:

export default defineConfig({})

The option can also be a function/async function. It supports all options which cli provided.

Or just prepare for it in package.json/scripts.

{
  "scripts": {
    "fnclip:add": "npx fnclip add --no-index --ts --dir src/utils/my-fn",
    "fnclip:clear": "npx fnclip clear --dir src/utils/my-fn"
  }
}

Now you can run npm fnclip:add pipe to add functions easily.

... and more!

Please refer to npx fnclip --help npx fnclip <command> --help

npx fnclip add pipe

npx fnclip remove pipe

npx fnclip clear # remove all fnclip functions

npx fnclip list # list all installed functions
npx fnclip list --remote # list all fnclip functions
