Breaking Changes 🔥

textlint-script build output compatible code for ES2015+.
It means that output code is not work on IE11.

Support Async Function ⭐️

Async/Await is supported by default.

Inline static resources by default ⭐️

For Web Browser support, textlint-script build inline static file by default.

textlint-script build inline Node fs calls with babel-plugin-static-fs for browser compatibility.

const fs = require("fs");
const path = require("path");
const text = fs.readFileSync(path.join(__dirname, ""), "utf-8");

will be

const text = "README CONTENT"

Web Browser does not support Node.js's fs module, this inlining feature aim to improve compatibility between Node.js and Web Browser.

ℹ️ @textlint/browser-run help you to test your textlint rule work on browser.

📝 You want to disable this behavior, set NO_INLINE env like NO_INLINE=1 textlint-scripts build.
