method Module.SourceMap.prototype.findEntry

Usage in Deno

import { Module } from "node:module";



SourceMap.prototype.findEntry(lineOffset: number,
columnOffset: number,
): SourceMapping

Given a line offset and column offset in the generated source file, returns an object representing the SourceMap range in the original file if found, or an empty object if not.

The object returned contains the following keys:

The returned value represents the raw range as it appears in the SourceMap, based on zero-indexed offsets, not 1-indexed line and column numbers as they appear in Error messages and CallSite objects.

To get the corresponding 1-indexed line and column numbers from a lineNumber and columnNumber as they are reported by Error stacks and CallSite objects, use sourceMap.findOrigin(lineNumber, columnNumber)

Parameters



lineOffset: number

The zero-indexed line number offset in the generated source



columnOffset: number

The zero-indexed column number offset in the generated source

Return Type
