Release Notes
evanw/esbuild (esbuild)
### [`v0.19.6`](https://togithub.com/evanw/esbuild/blob/HEAD/CHANGELOG.md#0196) [Compare Source](https://togithub.com/evanw/esbuild/compare/v0.19.5...v0.19.6) - Fix a constant folding bug with bigint equality This release fixes a bug where esbuild incorrectly checked for bigint equality by checking the equality of the bigint literal text. This is correct if the bigint doesn't have a radix because bigint literals without a radix are always in canonical form (since leading zeros are not allowed). However, this is incorrect if the bigint has a radix (e.g. `0x123n`) because the canonical form is not enforced when a radix is present. ```js // Original code console.log(!!0n, !!1n, 123n === 123n) console.log(!!0x0n, !!0x1n, 123n === 0x7Bn) // Old output console.log(false, true, true); console.log(true, true, false); // New output console.log(false, true, true); console.log(!!0x0n, !!0x1n, 123n === 0x7Bn); ``` - Add some improvements to the JavaScript minifier This release adds more cases to the JavaScript minifier, including support for inlining `String.fromCharCode` and `String.prototype.charCodeAt` when possible: ```js // Original code document.onkeydown = e => e.keyCode === 'A'.charCodeAt(0) && console.log(String.fromCharCode(55358, 56768)) // Old output (with --minify) document.onkeydown=o=>o.keyCode==="A".charCodeAt(0)&&console.log(String.fromCharCode(55358,56768)); // New output (with --minify) document.onkeydown=o=>o.keyCode===65&&console.log("🧀"); ``` In addition, immediately-invoked function expressions (IIFEs) that return a single expression are now inlined when minifying. This makes it possible to use IIFEs in combination with `@__PURE__` annotations to annotate arbitrary expressions as side-effect free without the IIFE wrapper impacting code size. For example: ```js // Original code const sideEffectFreeOffset = /* @__PURE__ */ (() => computeSomething())() use(sideEffectFreeOffset) // Old output (with --minify) const e=(()=>computeSomething())();use(e); // New output (with --minify) const e=computeSomething();use(e); ``` - Automatically prefix the `mask-composite` CSS property for WebKit ([#3493](https://togithub.com/evanw/esbuild/issues/3493)) The `mask-composite` property will now be prefixed as `-webkit-mask-composite` for older WebKit-based browsers. In addition to prefixing the property name, handling older browsers also requires rewriting the values since WebKit uses non-standard names for the mask composite modes: ```css /* Original code */ div { mask-composite: add, subtract, intersect, exclude; } /* New output (with --target=chrome100) */ div { -webkit-mask-composite: source-over, source-out, source-in, xor; mask-composite: add, subtract, intersect, exclude; } ``` - Avoid referencing `this` from JSX elements in derived class constructors ([#3454](https://togithub.com/evanw/esbuild/issues/3454)) When you enable `--jsx=automatic` and `--jsx-dev`, the JSX transform is supposed to insert `this` as the last argument to the `jsxDEV` function. I'm not sure exactly why this is and I can't find any specification for it, but in any case this causes the generated code to crash when you use a JSX element in a derived class constructor before the call to `super()` as `this` is not allowed to be accessed at that point. For example ```js // Original code class ChildComponent extends ParentComponent { constructor() { super() } } // Problematic output (with --loader=jsx --jsx=automatic --jsx-dev) import { jsxDEV } from "react/jsx-dev-runtime"; class ChildComponent extends ParentComponent { constructor() { super(/* @__PURE__ */ jsxDEV("div", {}, void 0, false, { fileName: "Configuration
