Interface: ExtractionConfig

Defined in: src/utils/javascript/JsAnalyzer.ts:4

Properties

collectDependencies?

optional collectDependencies: boolean

Defined in: src/utils/javascript/JsAnalyzer.ts:13

When false, dependency resolution is not enforced and extractions are marked as ready immediately when stopWhenReady is true.

friendlyName?

optional friendlyName: string

Defined in: src/utils/javascript/JsAnalyzer.ts:33

Name for easier identification of extractions.

match()

match: (node) => boolean | Node

Defined in: src/utils/javascript/JsAnalyzer.ts:8

Predicate that determines whether the current node should be considered a match.

Parameters

node

Node

Returns

boolean | Node

onlyProcessMatchContext?

optional onlyProcessMatchContext: boolean

Defined in: src/utils/javascript/JsAnalyzer.ts:29

If true, dependency collection is limited to the match context node itself.

stopWhenReady?

optional stopWhenReady: boolean

Defined in: src/utils/javascript/JsAnalyzer.ts:25

When true, traversal stops once the extraction is matched and all its dependencies (when collectDependencies=true) resolve. Only useful for small functions/vars without too many dependencies. Deeper dependency trees will usually have the unresolvable member expression here and there, for example:

 var Vmi = g.dX.window, Wr = Vmi?.yt?.config_ || Vmi?.ytcfg?.data_ || {};

Since Vmi.ytcfg is a dependency, it will never resolve because it comes from g.dX.window, which is an external object we don't have access to. In cases like this, stopWhenReady option does nothing useful.
