getModeForUsageLocation
Use program.getModeForUsageLocation
, which retrieves the correct compilerOptions
, instead of this function whenever possible. Calculates the final resolution mode for a given module reference node. This is the resolution mode explicitly provided via import attributes, if present, or the syntax the usage would have if emitted to JavaScript. In --module node16
or nodenext
, this may depend on the file's impliedNodeFormat
. In --module preserve
, it depends only on the input syntax of the reference. In other module
modes, when overriding import attributes are not provided, this function returns undefined
, as the result would have no impact on module resolution, emit, or type checking.
Parameters
The file the import or import-like reference is contained within
The module reference string
The compiler options for the program that owns the file. If the file belongs to a referenced project, the compiler options should be the options of the referenced project, not the referencing project.
