es2024as a compilation target, so esbuild now supports this in thetargetfield oftsconfig.jsonfiles, such as in the following configuration file:{ "compilerOptions": { "target": "ES2024" } }As a reminder, the only thing that esbuild uses this field for is determining whether or not to use legacy TypeScript behavior for class fields.

@​billyjanitsch.Allow automatic semicolon insertion after
get/setThis change fixes a grammar bug in the parser that incorrectly treated the following code as a syntax error:
class Foo { get *x() {} set *y() {} }The above code will be considered valid starting with this release. This change to esbuild follows a similar change to TypeScript which will allow this syntax starting with TypeScript 5.7.
Allow quoted property names in
--defineand--pure(#4008)The
defineandpureAPI options now accept identifier expressions containing quoted property names. Previously all identifiers in the identifier expression had to be bare identifiers. This change now makes--defineand--pureconsistent with--global-name, which already supported quoted property names. For example, the following is now possible:// The following code now transforms to "return true;\n" console.log(esbuild.transformSync( `return process.env['SOME-TEST-VAR']`, { define: { 'process.env["SOME-TEST-VAR"]': 'true' } }, ))Note that if you're passing values like this on the command line using esbuild's
--defineflag, then you'll need to know how to escape quote characters for your shell. You may find esbuild's JavaScript API more ergonomic and portable than writing shell code.Minify empty
