Description
Bumps esbuild from 0.17.19 to 0.25.0.
Release notes
Sourced from esbuild's releases.
v0.25.0
This release deliberately contains backwards-incompatible changes. To avoid automatically picking up releases like this, you should either be pinning the exact version of
esbuild
in yourpackage.json
file (recommended) or be using a version range syntax that only accepts patch upgrades such as^0.24.0
or~0.24.0
. See npm's documentation about semver for more information.
Restrict access to esbuild's development server (GHSA-67mh-4wv8-2f99)
This change addresses esbuild's first security vulnerability report. Previously esbuild set the
Access-Control-Allow-Origin
header to*
to allow esbuild's development server to be flexible in how it's used for development. However, this allows the websites you visit to make HTTP requests to esbuild's local development server, which gives read-only access to your source code if the website were to fetch your source code's specific URL. You can read more information in the report.Starting with this release, CORS will now be disabled, and requests will now be denied if the host does not match the one provided to
--serve=
. The default host is0.0.0.0
, which refers to all of the IP addresses that represent the local machine (e.g. both127.0.0.1
and192.168.0.1
). If you want to customize anything about esbuild's development server, you can put a proxy in front of esbuild and modify the incoming and/or outgoing requests.In addition, the
serve()
API call has been changed to return an array ofhosts
instead of a singlehost
string. This makes it possible to determine all of the hosts that esbuild's development server will accept.Thanks to
@sapphi-red
for reporting this issue.Delete output files when a build fails in watch mode (#3643)
It has been requested for esbuild to delete files when a build fails in watch mode. Previously esbuild left the old files in place, which could cause people to not immediately realize that the most recent build failed. With this release, esbuild will now delete all output files if a rebuild fails. Fixing the build error and triggering another rebuild will restore all output files again.
Fix correctness issues with the CSS nesting transform (#3620, #3877, #3933, #3997, #4005, #4037, #4038)
This release fixes the following problems:
Naive expansion of CSS nesting can result in an exponential blow-up of generated CSS if each nesting level has multiple selectors. Previously esbuild sometimes collapsed individual nesting levels using
:is()
to limit expansion. However, this collapsing wasn't correct in some cases, so it has been removed to fix correctness issues./* Original code */ .parent { > .a, > .b1 > .b2 { color: red; } } /* Old output (with --supported:nesting=false) */ .parent > :is(.a, .b1 > .b2) { color: red; } /* New output (with --supported:nesting=false) */ .parent > .a, .parent > .b1 > .b2 { color: red; }Thanks to
@tim-we
for working on a fix.The
&
CSS nesting selector can be repeated multiple times to increase CSS specificity. Previously esbuild ignored this possibility and incorrectly considered&&
to have the same specificity as&
. With this release, this should now work correctly:/* Original code (color should be red) */

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 withuseDefineForClassFields
set tofalse
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 tosuper()
(sincesuper()
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:
