import-move-codemod

Codemod to move imports from one module to another. Super useful in huge monorepos or huge migrations of 3rd party packages.

Usage

Inside your project root run For npm

npm i import-move-codemod --save-dev

or for yarn

yarn add import-move-codemod --dev

or for pnpm

pnpm add import-move-codemod --D

Before the run you need to create a file with a config, let say codemod.json

{
  "module": {
    "from": "one",
    "to": "two"
  },
  "specifiers": ["One"]
}

Then for example to run codemod against all the files in /src run

npx @codemod/cli -p import-move-codemod -o [email protected] --printer prettier /src

{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: ["One"]
}

import { One } from 'one'

//      ↓ ↓ ↓ ↓ ↓ ↓

import { One } from 'two';

{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: ["One", "Two"]
}

import { One, Two } from 'one'

//      ↓ ↓ ↓ ↓ ↓ ↓

import { One, Two } from 'two';

import { One as OneA, Two as TwoA } from 'one'

//      ↓ ↓ ↓ ↓ ↓ ↓

import { One as OneA, Two as TwoA } from 'two';

{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: ["Two"]
}

import { One, Two } from 'one'

//      ↓ ↓ ↓ ↓ ↓ ↓

import { Two } from 'two';
import { One } from 'one';

{

    from: "one",
    to: "two"
  },
  specifiers: ["default", "One", "Two"]
}

import ADefault, { One, Two, Three } from 'one'

//     ↓ ↓ ↓ ↓ ↓ ↓
