Drop support for older platforms (#3902)
This release drops support for the following operating system:
This is because the Go programming language dropped support for this operating system version in Go 1.23, and this release updates esbuild from Go 1.22 to Go 1.23. Go 1.23 now requires macOS 11 Big Sur or later.
Note that this only affects the binary esbuild executables that are published to the esbuild npm package. It's still possible to compile esbuild's source code for these older operating systems. If you need to, you can compile esbuild for yourself using an older version of the Go compiler (before Go version 1.23). That might look something like this:
git clone https://github.com/evanw/esbuild.git
cd esbuild
go build ./cmd/esbuild
./esbuild --version

Fix class field decorators in TypeScript if useDefineForClassFields
is false
(#3913)
Setting the useDefineForClassFields
flag to false
in tsconfig.json
means class fields use the legacy TypeScript behavior instead of the standard JavaScript behavior. Specifically they use assign semantics instead of define semantics (e.g. setters are triggered) and fields without an initializer are not initialized at all. However, when this legacy behavior is combined with standard JavaScript decorators, TypeScript switches to always initializing all fields, even those without initializers. Previously esbuild incorrectly continued to omit field initializers for this edge case. These field initializers in this case should now be emitted starting with this release.

Avoid incorrect cycle warning with tsconfig.json
multiple inheritance (#3898)
TypeScript 5.0 introduced multiple inheritance for tsconfig.json
files where extends
can be an array of file paths. Previously esbuild would incorrectly treat files encountered more than once when processing separate subtrees of the multiple inheritance hierarchy as an inheritance cycle. With this release, tsconfig.json
files containing this edge case should work correctly without generating a warning.

Handle Yarn Plug'n'Play stack overflow with tsconfig.json
(#3915)
Previously a tsconfig.json
file that extends
another file in a package with an exports
map could cause a stack overflow when Yarn's Plug'n'Play resolution was active. This edge case should work now starting with this release.

Work around more issues with Deno 1.31+ (#3917)
This version of Deno broke the stdin
and stdout
properties on command objects for inherited streams, which matters when you run esbuild's Deno module as the entry point (i.e. when import.meta.main
is true
). Previously esbuild would crash in Deno 1.31+ if you ran esbuild like that. This should be fixed starting with this release.
