Support TypeScript experimental decorators on abstract class fields (#3684)
With this release, you can now use TypeScript experimental decorators on abstract class fields. This was silently compiled incorrectly in esbuild 0.19.7 and below, and was an error from esbuild 0.19.8 to esbuild 0.20.1. Code such as the following should now work correctly:
// Original code
const log = (x: any, y: string) => console.log(y)
abstract class Foo { @log abstract foo: string }
new class extends Foo { foo = '' }
// Old output (with --loader=ts --tsconfig-raw={"compilerOptions":{"experimentalDecorators":true}})
const log = (x, y) => console.log(y);
class Foo {
}
new class extends Foo {
foo = "";
}();
// New output (with --loader=ts --tsconfig-raw={"compilerOptions":{"experimentalDecorators":true}})
const log = (x, y) => console.log(y);
class Foo {
}
__decorateClass([
log
], Foo.prototype, "foo", 2);
new class extends Foo {
foo = "";
}();
JSON loader now preserves __proto__ properties (#3700)
Copying JSON source code into a JavaScript file will change its meaning if a JSON object contains the __proto__ key. A literal __proto__ property in a JavaScript object literal sets the prototype of the object instead of adding a property named __proto__, while a literal __proto__ property in a JSON object literal just adds a property named __proto__. With this release, esbuild will now work around this problem by converting JSON to JavaScript with a computed property key in this case:
// Original code
import data from 'data:application/json,{"__proto__":{"fail":true}}'
if (Object.getPrototypeOf(data)?.fail) throw 'fail'
// Old output (with --bundle)
(() => {
// <data:application/json,{"proto":{"fail":true}}>
var json_proto_fail_true_default = { proto: { fail: true } };
// entry.js
if (Object.getPrototypeOf(json_proto_fail_true_default)?.fail)
throw "fail";
})();
