SingleFile Escaped 📦🧣

Vite Plugin to export code as escaped text after bundling (singlefile)

This Vite plugin allows you to escape the output of vite-plugin-singlefile and optionally wrap it with custom strings before and after. It uses jsesc to escape the content, making it safe for embedding in specific environments or as part of a larger string.

npm install vite-plugin-singlefile-escaped --save-dev

or if you prefer using Yarn:

yarn add vite-plugin-singlefile-escaped --dev

To use vite-plugin-singlefile-escaped in your Vite project, import it into your vite.config.js or vite.config.ts and add it to the plugins array. You also need to have vite-plugin-singlefile installed and configured, as this plugin works on its output.

// vite.config.js
import { viteSingleFile } from "vite-plugin-singlefile";
import viteSingleFileEscaped from "vite-plugin-singlefile-escaped";

export default {
  plugins: [
    viteSingleFile(),
    viteSingleFileEscaped()
  ],
};

viteSingleFileEscaped accepts two optional parameters to customize the wrapping of the escaped content and an optional posibility of a configuration for more precise escaping

function viteSingleFileEscaped(wrapBefore: string, wrapAfter: string, config: object): void

• wrapBefore: A string to prepend before the escaped content.
• wrapAfter: A string to append after the escaped content.
• config: A destructured object that allows to add special configurations Jsesc Docs

If not provided, these parameters default to an empty string, meaning no wrapping will be applied beyond escaping the content. Example

Here is an example configuration that escapes the entire output of your single-file bundle and wraps it in a JavaScript log function:

// vite.config.js
import { viteSingleFile } from "vite-plugin-singlefile";
import viteSingleFileEscaped from "vite-plugin-singlefile-escaped";

export default {
  plugins: [
    viteSingleFile(),
    viteSingleFileEscaped('console.log("', ");", { quotes: "double" }),
  ],
};

// dist/index.html
console.log("<ESCAPED_CODE_PLACEHOLDER>");

This setup escapes the single-file output and wraps it with console.log(" at the beginning and "); at the end, making it ready to be logged directly to the console as part of a larger script or debugging tool.
