VS Code Regex find and replace require syntax with import syntax

README.md

Simple require imports, for example const bar = require("foo"):

• Regex: (const|var|let)\b\s+(\w+)\s+=\s+require\s*\(["']([\/\w\-]+)["']\)\n
• Replace: import $2 from "$3"\n

One-liner require & config/compute, for example const router = require("express").Router({ mergeParams: true }):

• Regex: (const|var|let)\b\s+(\w+)\s+=\s+require\s*\(["'](\w+)["']\)(?=\S+)
• Replace: import $3 from "$3" \n$1 $2 = $3

WARNING: Using this regex one can end up with duplicate variable names (when $2 === $3).

Relative module imports, for example const bar = require("./bar/foo"):

• Regex: (const|var|let)\b\s+(\w+)\s+=\s+require\s*\(["']([\.\/\w\-]+)["']\)\n
• Replace: import $2 from "$3"\n

One-line import, no variable, for example: require("module"):

• Regex: require\s*\(["']([\/\w\-]+)["']\)\n
• Replace: import "$1"\n

Append .mjs or .js to import statements:

• Regex: import ([\w\-_]+)\s+from\s+["'](?=\.)([\w\-\.\/]+)["']
• Replace: import $1 from "$2.js"

Other replacements

• module.exports = with export default
• exports.([\w\-_]+) with export const $1
