Chai now only supports EcmaScript Modules (ESM). This means your tests will need to either have import {...} from 'chai' or import('chai'). require('chai') will cause failures in nodejs. If you're using ESM and seeing failures, it may be due to a bundler or transpiler which is incorrectly converting import statements into require calls.
Dropped support for Internet Explorer.
Dropped support for NodeJS < 18.
Minimum supported browsers are now Firefox 100, Safari 14.1, Chrome 100, Edge 100. Support for browsers prior to these versions is "best effort" (bug reports on older browsers will be assessed individually and may be marked as wontfix).
We've put out a few alpha versions and tested them out in various projects with good success. This RC includes all those changes plus any fixes that we've discovered since then.
Please try it out in your projects and let us know if you run into any issues so we can make fixes before version 5!
Fix TypeScript-specific class transform edge case (#3559)
The previous release introduced an optimization that avoided transforming super() in the class constructor for TypeScript code compiled with useDefineForClassFields set to false if all class instance fields have no initializers. The rationale was that in this case, all class instance fields are omitted in the output so no changes to the constructor are needed. However, if all of this is the case and there are #private instance fields with initializers, those private instance field initializers were still being moved into the constructor. This was problematic because they were being inserted before the call to super() (since super() is now no longer transformed in that case). This release introduces an additional optimization that avoids moving the private instance field initializers into the constructor in this edge case, which generates smaller code, matches the TypeScript compiler's output more closely, and avoids this bug:
// Original code
class Foo extends Bar {
#private = 1;
public: any;
constructor() {
super();
}
}
// Old output (with esbuild v0.19.9)
class Foo extends Bar {
constructor() {
super();
this.#private = 1;
}
#private;
}
// Old output (with esbuild v0.19.10)
class Foo extends Bar {
constructor() {
this.#private = 1;
super();
}
#private;
}
// New output
class Foo extends Bar {
#private = 1;
constructor() {
super();
}
}
Minifier: allow reording a primitive past a side-effect (#3568)
The minifier previously allowed reordering a side-effect past a primitive, but didn't handle the case of reordering a primitive past a side-effect. This additional case is now handled:
