Bump esbuild and tsup

Open dependabot[bot] opened this issue 5 months ago • 0 comments

Bumps esbuild to 0.25.8 and updates ancestor dependency tsup. These dependencies need to be updated together.

Updates esbuild from 0.12.29 to 0.25.8

Release notes

v0.25.8
Fix another TypeScript parsing edge case (#4248)

This fixes a regression with a change in the previous release that tries to more accurately parse TypeScript arrow functions inside the ?: operator. The regression specifically involves parsing an arrow function containing a #private identifier inside the middle of a ?: ternary operator inside a class body. This was fixed by propagating private identifier state into the parser clone used to speculatively parse the arrow function body. Here is an example of some affected code:
class CachedDict {
  #has = (a: string) => dict.has(a);
  has = window
    ? (word: string): boolean => this.#has(word)
    : this.#has;
}
Fix a regression with the parsing of source phase imports

The change in the previous release to parse source phase imports failed to properly handle the following cases:
import source from 'bar'
import source from from 'bar'
import source type foo from 'bar'
Parsing for these cases should now be fixed. The first case was incorrectly treated as a syntax error because esbuild was expecting the second case. And the last case was previously allowed but is now forbidden. TypeScript hasn't added this feature yet so it remains to be seen whether the last case will be allowed, but it's safer to disallow it for now. At least Babel doesn't allow the last case when parsing TypeScript, and Babel was involved with the source phase import specification.
v0.25.7
Parse and print JavaScript imports with an explicit phase (#4238)

This release adds basic syntax support for the defer and source import phases in JavaScript:
defer

This is a stage 3 proposal for an upcoming JavaScript feature that will provide one way to eagerly load but lazily initialize imported modules. The imported module is automatically initialized on first use. Support for this syntax will also be part of the upcoming release of TypeScript 5.9. The syntax looks like this:
import defer * as foo from "<specifier>";
const bar = await import.defer("<specifier>");
Note that this feature deliberately cannot be used with the syntax import defer foo from "<specifier>" or import defer { foo } from "<specifier>".
source

This is a stage 3 proposal for an upcoming JavaScript feature that will provide another way to eagerly load but lazily initialize imported modules. The imported module is returned in an uninitialized state. Support for this syntax may or may not be a part of TypeScript 5.9 (see this issue for details). The syntax looks like this:
import source foo from "<specifier>";
const bar = await import.source("<specifier>");

Changelog

Sourced from esbuild's changelog.

Changelog: 2021

This changelog documents all esbuild versions published in the year 2021 (versions 0.8.29 through 0.14.10).

0.14.10
Enable tree shaking of classes with lowered static fields (#175)

If the configured target environment doesn't support static class fields, they are converted into a call to esbuild's __publicField function instead. However, esbuild's tree-shaking pass treated this call as a side effect, which meant that all classes with static fields were ineligible for tree shaking. This release fixes the problem by explicitly ignoring calls to the __publicField function during tree shaking side-effect determination. Tree shaking is now enabled for these classes:
// Original code
class Foo { static foo = 'foo' }
class Bar { static bar = 'bar' }
new Bar()
// Old output (with --tree-shaking=true --target=es6)

class Foo {

}

__publicField(Foo, "foo", "foo");

class Bar {

}

__publicField(Bar, "bar", "bar");

new Bar();
// New output (with --tree-shaking=true --target=es6)

class Bar {

}

__publicField(Bar, "bar", "bar");

new Bar();
Treat --define:foo=undefined as an undefined literal instead of an identifier (#1407)

References to the global variable undefined are automatically replaced with the literal value for undefined, which appears as void 0 when printed. This allows for additional optimizations such as collapsing undefined ?? bar into just bar. However, this substitution was not done for values specified via --define:. As a result, esbuild could potentially miss out on certain optimizations in these cases. With this release, it's now possible to use --define: to substitute something with an undefined literal:
// Original code
let win = typeof window !== 'undefined' ? window : {}
// Old output (with --define:window=undefined --minify)

let win=typeof undefined!="undefined"?undefined:{};
// New output (with --define:window=undefined --minify)

let win={};
Add the --drop:debugger flag (#1809)

Passing this flag causes all debugger; statements to be removed from the output. This is similar to the drop_debugger: true flag available in the popular UglifyJS and Terser JavaScript minifiers.
