import-move-codemod

npm

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 import-move-codemod=@codemod.json --printer prettier /src 

What refactorings are available

Move of one or multiple named imports from one module to another

{
  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';

Move named imports and default in one go

{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: ["default", "One", "Two"]
}
import ADefault, { One, Two, Three } from 'one'
 
//     ↓ ↓ ↓ ↓ ↓ ↓
 
import ADefault, { One, Two } from 'two';
import { Three } from 'one';
{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: ["default", "Two"]
}
import One, { Two } from 'one'
 
 //     ↓ ↓ ↓ ↓ ↓ ↓
 
import One, { Two } from 'two';

Move everything i.e. module rename

{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: ["*"]
}
import ADefault, { One, Two, Three } from 'one'
 
//      ↓ ↓ ↓ ↓ ↓ ↓
 
import ADefault, { One, Two, Three } from 'two';
 

Move named imports and rename them

{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: {
    One: "OneR",
    Two: "TwoR"
  }
}
import ADefault, { One, Two } from 'one'
 
//      ↓ ↓ ↓ ↓ ↓ ↓
 
import { OneR, TwoR } from 'two';
import ADefault from 'one';
import { One, Two } from 'one'
 
//      ↓ ↓ ↓ ↓ ↓ ↓
 
import { OneR, TwoR } from 'two';

Move default import to named

{
  module: {
    from: "one",
    to: "two"
  },
  specifiers: { default: "One" }
}
import One, { Two } from 'one'
 
//      ↓ ↓ ↓ ↓ ↓ ↓
 
import { One } from 'two';
import { Two } from 'one';
import One from 'one'
 
//      ↓ ↓ ↓ ↓ ↓ ↓
 
import { One } from 'two';

import { One, Two, Three } from 'one';
import One from 'one'
 
//      ↓ ↓ ↓ ↓ ↓ ↓
 
import One from 'two';
