Fix the alias feature to always prefer the longest match (#2963)
It's possible to configure conflicting aliases such as --alias:a=b and --alias:a/c=d, which is ambiguous for the import path a/c/x (since it could map to either b/c/x or d/x). Previously esbuild would pick the first matching alias, which would non-deterministically pick between one of the possible matches. This release fixes esbuild to always deterministically pick the longest possible match.
Minify calls to some global primitive constructors (#2962)
With this release, esbuild's minifier now replaces calls to Boolean/Number/String/BigInt with equivalent shorter code when relevant:
// Old output (with --minify)
console.log(Boolean(a?(b|c)!==0:(c&d)!==0),Number(e?"1":"2"),String(e?"1":"2"),BigInt(e?1n:2n));
// New output (with --minify)
console.log(!!(a?b|c:c&d),+(e?"1":"2"),e?"1":"2",e?1n:2n);
Adjust some feature compatibility tables for node (#2940)
This release makes the following adjustments to esbuild's internal feature compatibility tables for node, which tell esbuild which versions of node are known to support all aspects of that feature:
class-private-brand-checks: node v16.9+ => node v16.4+ (a decrease)
Each of these adjustments was identified by comparing against data from the node-compat-table package and was manually verified using old node executables downloaded from https://nodejs.org/download/release/.
v0.17.10
Update esbuild's handling of CSS nesting to match the latest specification changes (#1945)
The syntax for the upcoming CSS nesting feature has recently changed. The @nest prefix that was previously required in some cases is now gone, and nested rules no longer have to start with & (as long as they don't start with an identifier or function token).
This release updates esbuild's pass-through handling of CSS nesting syntax to match the latest specification changes. So you can now use esbuild to bundle CSS containing nested rules and try them out in a browser that supports CSS nesting (which includes nightly builds of both Chrome and Safari).
However, I'm not implementing lowering of nested CSS to non-nested CSS for older browsers yet. While the syntax has been decided, the semantics are still in flux. In particular, there is still some debate about changing the fundamental way that CSS nesting works. For example, you might think that the following CSS is equivalent to a .outer .inner button { ... } rule:
