Support flags in regular expressions for the API (#4121)
The JavaScript plugin API for esbuild takes JavaScript regular expression objects for the
filter
option. Internally these are translated into Go regular expressions. However, this translation previously ignored theflags
property of the regular expression. With this release, esbuild will now translate JavaScript regular expression flags into Go regular expression flags. Specifically the JavaScript regular expression/\.[jt]sx?$/i
is turned into the Go regular expression`(?i)\.[jt]sx?$`
internally inside of esbuild's API. This should make it possible to use JavaScript regular expressions with thei
flag. Note that JavaScript and Go don't support all of the same regular expression features, so this mapping is only approximate.Fix node-specific annotations for string literal export names (#4100)
When node instantiates a CommonJS module, it scans the AST to look for names to expose via ESM named exports. This is a heuristic that looks for certain patterns such as
exports.NAME = ...
ormodule.exports = { ... }
. This behavior is used by esbuild to "annotate" CommonJS code that was converted from ESM with the original ESM export names. For example, when converting the fileexport let foo, bar
from ESM to CommonJS, esbuild appends this to the end of the file:However, this feature previously didn't work correctly for export names that are not valid identifiers, which can be constructed using string literal export names. The generated code contained a syntax error. That problem is fixed in this release:
Basic support for index source maps (#3439, #4109)
The source map specification has an optional mode called index source maps that makes it easier for tools to create an aggregate JavaScript file by concatenating many smaller JavaScript files with source maps, and then generate an aggregate source map by simply providing the original source maps along with some offset information. My understanding is that this is rarely used in practice. I'm only aware of two uses of it in the wild: ClojureScript and Turbopack.
This release provides basic support for indexed source maps. However, the implementation has not been tested on a real app (just on very simple test input). If you are using index source maps in a real app, please try this out and report back if anything isn't working for you.
Note that this is also not a complete implementation. For example, index source maps technically allows nesting source maps to an arbitrary depth, while esbuild's implementation in this release only supports a single level of nesting. It's unclear whether supporting more than one level of nesting is important or not given the lack of available test cases.

Fix incorrect paths in inline source maps (#4070, #4075, #4105)
This fixes a regression from version 0.25.0 where esbuild didn't correctly resolve relative paths contained within source maps in inline
sourceMappingURL
data URLs. The paths were incorrectly being passed through as-is instead of being resolved relative to the source file containing thesourceMappingURL
comment, which was due to the data URL not being a file URL. This regression has been fixed, and this case now has test coverage.Fix invalid generated source maps (#4080, #4082, #4104, #4107)
This release fixes a regression from version 0.24.1 that could cause esbuild to generate invalid source maps. Specifically under certain conditions, esbuild could generate a mapping with an out-of-bounds source index. It was introduced by code that attempted to improve esbuild's handling of "null" entries in source maps (i.e. mappings with a generated position but no original position). This regression has been fixed.
This fix was contributed by @jridgewell.
Fix a regression with non-file source map paths (#4078)
The format of paths in source maps that aren't in the
file
namespace was unintentionally changed in version 0.25.0. Path namespaces is an esbuild-specific concept that is optionally available for plugins to use to distinguish paths fromfile
paths and from paths meant for other plugins. Previously the namespace was prepended to the path joined with a:
character, but version 0.25.0 unintentionally failed to prepend the namespace. The previous behavior has been restored.Fix a crash with
switch
optimization (#4088)The new code in the previous release to optimize dead code in switch statements accidentally introduced a crash in the edge case where one or more switch case values include a function expression. This is because esbuild now visits the case values first to determine whether any cases are dead code, and then visits the case bodies once the dead code status is known. That triggered some internal asserts that guard against traversing the AST in an unexpected order. This crash has been fixed by changing esbuild to expect the new traversal ordering. Here's an example of affected code:
Update Go from 1.23.5 to 1.23.7 (#4076, #4077)
This should have no effect on existing code as this version change does not change Go's operating system support. It may remove certain reports from vulnerability scanners that detect which version of the Go compiler esbuild uses.
