fix(devtools-bundler-core): skip primitive values when walking AST children - #539
AlemTuzlak wants to merge 2 commits into
Conversation
…ildren getChildKeys caches the object-valued keys of the first node it sees for a type. A regex Literal has an object `value`, so `value` was cached for every Literal. A later string Literal then reached `'type' in value` with a string, which throws. addSourceToJsx catches the error and returns nothing, so after one regex literal no file got data-tsd-source attributes. forEachChild now skips every non-object value. Fixes #523

Narrow the changeset’s impact claim.
The module-scoped cache can cause a later traversal to throw when a cached child key contains a primitive. addSourceToJsx catches that exception and returns for the current file. It does not disable injection for every later file.
Suggested changeset wording
-Source injection no longer stops after the dev server parses a regex literal. Before this fix, one regex literal anywhere in the module graph made every later file get zero `data-tsd-source` attributes.
+Source injection no longer stops when a later AST traversal encounters a primitive under a cached child key. Before this fix, a regex literal could cache `value` for `Literal`; a later file with a string literal could then abort its traversal and receive zero `data-tsd-source` attributes.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

After the dev server parses one regex literal, source injection silently adds zero
data-tsd-sourceattributes to every later file. This PR makes the AST walker skip primitive values, so a cached child key can no longer throw.🎯 Changes
getChildKeyscaches the object-valued keys of the first node of each type. A regexLiteralhas an objectvalue, sovaluegoes into the cache for allLiteralnodes.Literalthen reaches'type' in valuewith a string, which throwsTypeError: Cannot use 'in' operator.addSourceToJsxcatches the error and returns nothing.forEachChildnow skips any value that is not an object.
