getModeForResolutionAtIndex
Use program.getModeForResolutionAtIndex, which retrieves the correct compilerOptions, instead of this function whenever possible. Calculates the final resolution mode for an import at some index within a file's imports list. 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
File to fetch the resolution mode within
Index into the file's complete resolution list to get the resolution of - this is a concatenation of the file's imports and module augmentations
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.
