🚀 Features

🔥 Import any file as raw content with zero config in ESBuild or TSUP — text, base64, binary, docx templates & more!
⚡️ Fast, smart, and extensible → esbuild-raw-plugin

• 🔧 Supports ?raw, ?text, ?base64, ?dataurl, ?binary, and ?file query suffixes
• 🧠 Smart fallback to extensions like .ts, .tsx, index.[ext], etc.
• 🔍 Custom loader mapping (e.g., module.scss → text, png → dataurl)
• ⚡ Ultra-fast using regex-based native onLoad filter (Go-native perf)
• 🪶 Works seamlessly with both Tsup and ESBuild

📦 Installation

or

yarn add esbuild-raw-plugin --dev

or

pnpm add esbuild-raw-plugin --save-dev

🛠 Usage

➤ With ESBuild

import { build } from "esbuild";
import { raw } from "esbuild-raw-plugin";

build({
  entryPoints: ["src/index.js"],
  bundle: true,
  outfile: "out.js",
  plugins: [raw()],
});

➤ With TSUP

import { defineConfig } from "tsup";
import { raw } from "esbuild-raw-plugin";

export default defineConfig({
  entry: ["src/index.ts"],
  outDir: "dist",
  esbuildPlugins: [raw()],
});

---

🧠 TypeScript Support

Add this to your declarations.d.ts file:

declare module "*?raw" {
  const content: string;
  export default content;
}

For other suffixes (?base64, ?binary, etc.), add similar declarations if needed.

---

📥 Importing Raw Files

import content from "./example.js?raw";

console.log(content); // Entire file content as string or Buffer

✅ Simplified Imports

You don’t need to specify full filenames or extensions:

import code from "./utils?raw"; // Resolves to utils/index.ts, utils.js, etc.

Great for:

• Library or folder-level imports
• Auto-resolving .ts, .tsx, .css, .scss, etc.

⚙️ Plugin Options

export interface RawPluginOptions {
  ext?: string[];
  loader?: "text" | "base64" | "dataurl" | "file" | "binary" | "default";
  customLoaders?: Record<string, "text" | "base64" | "dataurl" | "file" | "binary" | "default">;
  name?: string;
}

🔧 Option Details

• ext: Extensions to resolve if the file or folder is missing. Defaults to common types like ts, tsx, module.css, etc.

• loader: Default loader if no ?query is specified. Usually "text".

• customLoaders: Per-extension loader mapping. Example:

  {
    "module.scss": "text",
    "png": "dataurl",
    "docx": "file"
  }

• name: Optional plugin name override for debugging or deduplication.

🧪 Supported Query Loaders

Import with query-based syntax:

import doc from "./readme.md?text";
import logo from "./logo.png?base64";
import wasm from "./core.wasm?binary";

Query Suffix	Description
?raw	Uses the default loader (options.loader ?? "text")
?text	Loads file as UTF-8 text
?base64	Returns base64 string
?dataurl	Returns full data URL
?file	Emits file to output dir
?binary	Returns raw Buffer

  return (
    <LiveProvider code={exampleCode}>
      <LiveEditor />
      <LiveError />
