<h2>v0.21.3</h2>
<ul>
<li>
<p>Implement the decorator metadata proposal (<a
href="https://redirect.github.com/evanw/esbuild/issues/3760">#3760</a>)</p>
<p>This release implements the <a
href="https://github.com/tc39/proposal-decorator-metadata">decorator
metadata proposal</a>, which is a sub-proposal of the <a
href="https://github.com/tc39/proposal-decorators">decorators
proposal</a>. Microsoft shipped the decorators proposal in <a
href="https://devblogs.microsoft.com/typescript/announcing-typescript-5-0/#decorators">TypeScript
5.0</a> and the decorator metadata proposal in <a
href="https://devblogs.microsoft.com/typescript/announcing-typescript-5-2/#decorator-metadata">TypeScript
5.2</a>, so it's important that esbuild also supports both of these
features. Here's a quick example:</p>
<pre lang="js"><code>// Shim the &quot;Symbol.metadata&quot; symbol
Symbol.metadata ??= Symbol('Symbol.metadata')
<p>const track = (_, context) =&gt; {
(context.metadata.names ||= []).push(context.name)
}</p>
<p>class Foo {
<a href="https://github.com/track"><code>@​track</code></a> foo = 1
<a href="https://github.com/track"><code>@​track</code></a> bar = 2
}</p>
<p>// Prints [&quot;foo&quot;, &quot;bar&quot;]
console.log(Foo[Symbol.metadata].names)
</code></pre></p>
<p><strong>⚠️ WARNING ⚠️</strong></p>
<p>This proposal has been marked as &quot;stage 3&quot; which means
&quot;recommended for implementation&quot;. However, it's still a work
in progress and isn't a part of JavaScript yet, so keep in mind that any
code that uses JavaScript decorator metadata may need to be updated as
the feature continues to evolve. If/when that happens, I will update
esbuild's implementation to match the specification. I will not be
supporting old versions of the specification.</p>
</li>
<li>
<p>Fix bundled decorators in derived classes (<a
href="https://redirect.github.com/evanw/esbuild/issues/3768">#3768</a>)</p>
<p>In certain cases, bundling code that uses decorators in a derived
class with a class body that references its own class name could
previously generate code that crashes at run-time due to an incorrect
variable name. This problem has been fixed. Here is an example of code
that was compiled incorrectly before this fix:</p>
<pre lang="js"><code>class Foo extends Object {
  @(x =&gt; x) foo() {
    return Foo
  }
}
console.log(new Foo().foo())
</code></pre>
</li>
<li>
<p>Fix <code>tsconfig.json</code> files inside symlinked directories (<a
href="https://redirect.github.com/evanw/esbuild/issues/3767">#3767</a>)</p>
<p>This release fixes an issue with a scenario involving a
<code>tsconfig.json</code> file that <code>extends</code> another file
from within a symlinked directory that uses the <code>paths</code>
feature. In that case, the implicit <code>baseURL</code> value should be
based on the real path (i.e. after expanding all symbolic links) instead
of the original path. This was already done for other files that esbuild
resolves but was not yet done for <code>tsconfig.json</code> because
it's special-cased (the regular path resolver can't be used because the
information inside <code>tsconfig.json</code> is involved in path
resolution). Note that this fix no longer applies if the
<code>--preserve-symlinks</code> setting is enabled.</p>
</li>
</ul>
<h2>v0.21.2</h2>
<ul>
<li>
<p>Correct <code>this</code> in field and accessor decorators (<a
href="https://redirect.github.com/evanw/esbuild/issues/3761">#3761</a>)</p>
<p>This release changes the value of <code>this</code> in initializers
for class field and accessor decorators from the module-level
<code>this</code> value to the appropriate <code>this</code> value for
the decorated element (either the class or the instance). It was
previously incorrect due to lack of test coverage. Here's an example of
a decorator that doesn't work without this change:</p>
<pre lang="js"><code>const dec = () =&gt; function() { this.bar = true }
</code></pre>
</li>
</ul>

changelog</a>.</em></p>
<blockquote>
<h1>Changelog: 2023</h1>
<p>This changelog documents all esbuild versions published in the year
2023 (versions 0.16.13 through 0.19.11).</p>
<h2>0.19.11</h2>
<ul>
<li>
<p>Fix TypeScript-specific class transform edge case (<a
href="https://redirect.github.com/evanw/esbuild/issues/3559">#3559</a>)</p>
<p>The previous release introduced an optimization that avoided
transforming <code>super()</code> in the class constructor for
TypeScript code compiled with <code>useDefineForClassFields</code> set
to <code>false</code> 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 <em>and</em> there are
<code>#private</code> 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
<code>super()</code> (since <code>super()</code> 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:</p>
<pre lang="ts"><code>// Original code
class Foo extends Bar {
  #private = 1;
  public: any;
  constructor() {
    super();
  }
}
<p>// Old output (with esbuild v0.19.9)
class Foo extends Bar {
constructor() {
super();
this.#private = 1;
}
#private;
}</p>
<p>// Old output (with esbuild v0.19.10)
class Foo extends Bar {
constructor() {
this.#private = 1;
super();
}
#private;
}</p>
<p>// New output
class Foo extends Bar {
#private = 1;
constructor() {
super();
}
}
</code></pre></p>
</li>
<li>
<p>Minifier: allow reording a primitive past a side-effect (<a
href="https://redirect.github.com/evanw/esbuild/issues/3568">#3568</a>)</p>
<p>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:</p>
