JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
@esbuild/linux-x64
Advanced tools
The @esbuild/linux-x64 npm package is a pre-compiled binary of esbuild for Linux x64 systems. Esbuild is an extremely fast JavaScript bundler and minifier. It compiles JavaScript and TypeScript code, bundling it together for use in the browser. It can also minify CSS. This package is specifically built to run on Linux x64 environments, providing a seamless experience for developers working on these systems.
JavaScript and TypeScript bundling
This feature allows you to bundle JavaScript and TypeScript files into a single file. The code sample demonstrates how to bundle an entry file named 'app.js' into an output file named 'out.js'.
require('esbuild').build({
entryPoints: ['app.js'],
bundle: true,
outfile: 'out.js',
}).catch(() => process.exit(1))
Minifying JavaScript
This feature enables the minification of JavaScript files to reduce their size for production. The code sample shows how to minify a JavaScript file named 'app.js' into a smaller file named 'out.min.js'.
require('esbuild').build({
entryPoints: ['app.js'],
minify: true,
outfile: 'out.min.js',
}).catch(() => process.exit(1))
CSS bundling and minification
Esbuild can also bundle and minify CSS files. This code sample demonstrates bundling and minifying a CSS file named 'app.css' into 'out.css'.
require('esbuild').build({
entryPoints: ['app.css'],
bundle: true,
minify: true,
outfile: 'out.css',
}).catch(() => process.exit(1))
Webpack is a powerful module bundler for JavaScript applications. It offers a wide range of plugins and loaders to transform and bundle assets. Compared to @esbuild/linux-x64, webpack is more configurable but generally slower in terms of build time.
Rollup is another JavaScript module bundler that focuses on producing smaller bundles by eliminating unused code. It is particularly well-suited for libraries. Rollup is more similar to esbuild in terms of speed but does not match esbuild's raw performance.
Parcel is a web application bundler that offers out-of-the-box support for many web development languages and frameworks. It is known for its zero-configuration approach. Parcel provides a good balance between speed and ease of use but is generally slower than esbuild.
This is the Linux 64-bit binary for esbuild, a JavaScript bundler and minifier. See https://github.com/evanw/esbuild for details.
0.20.1
Fix a bug with the CSS nesting transform (#3648)
This release fixes a bug with the CSS nesting transform for older browsers where the generated CSS could be incorrect if a selector list contained a pseudo element followed by another selector. The bug was caused by incorrectly mutating the parent rule's selector list when filtering out pseudo elements for the child rules:
/* Original code */
.foo {
&:after,
& .bar {
color: red;
}
}
/* Old output (with --supported:nesting=false) */
.foo .bar,
.foo .bar {
color: red;
}
/* New output (with --supported:nesting=false) */
.foo:after,
.foo .bar {
color: red;
}
Constant folding for JavaScript inequality operators (#3645)
This release introduces constant folding for the < > <= >=
operators. The minifier will now replace these operators with true
or false
when both sides are compile-time numeric or string constants:
// Original code
console.log(1 < 2, '🍕' > '🧀')
// Old output (with --minify)
console.log(1<2,"🍕">"🧀");
// New output (with --minify)
console.log(!0,!1);
Better handling of __proto__
edge cases (#3651)
JavaScript object literal syntax contains a special case where a non-computed property with a key of __proto__
sets the prototype of the object. This does not apply to computed properties or to properties that use the shorthand property syntax introduced in ES6. Previously esbuild didn't correctly preserve the "sets the prototype" status of properties inside an object literal, meaning a property that sets the prototype could accidentally be transformed into one that doesn't and vice versa. This has now been fixed:
// Original code
function foo(__proto__) {
return { __proto__: __proto__ } // Note: sets the prototype
}
function bar(__proto__, proto) {
{
let __proto__ = proto
return { __proto__ } // Note: doesn't set the prototype
}
}
// Old output
function foo(__proto__) {
return { __proto__ }; // Note: no longer sets the prototype (WRONG)
}
function bar(__proto__, proto) {
{
let __proto__2 = proto;
return { __proto__: __proto__2 }; // Note: now sets the prototype (WRONG)
}
}
// New output
function foo(__proto__) {
return { __proto__: __proto__ }; // Note: sets the prototype (correct)
}
function bar(__proto__, proto) {
{
let __proto__2 = proto;
return { ["__proto__"]: __proto__2 }; // Note: doesn't set the prototype (correct)
}
}
Fix cross-platform non-determinism with CSS color space transformations (#3650)
The Go compiler takes advantage of "fused multiply and add" (FMA) instructions on certain processors which do the operation x*y + z
without intermediate rounding. This causes esbuild's CSS color space math to differ on different processors (currently ppc64le
and s390x
), which breaks esbuild's guarantee of deterministic output. To avoid this, esbuild's color space math now inserts a float64()
cast around every single math operation. This tells the Go compiler not to use the FMA optimization.
Fix a crash when resolving a path from a directory that doesn't exist (#3634)
This release fixes a regression where esbuild could crash when resolving an absolute path if the source directory for the path resolution operation doesn't exist. While this situation doesn't normally come up, it could come up when running esbuild concurrently with another operation that mutates the file system as esbuild is doing a build (such as using git
to switch branches). The underlying problem was a regression that was introduced in version 0.18.0.
