用于定位源码的命令行小工具

Source-location

This is a cli to get location of original source code.

Why use

Since the production environment code is compiled code, the rows and columns that collect the error information cannot correspond in the source code. Source-location is a command-line widget used to locate the source code to help locate the source location quickly and improve efficiency. Before using this cli, you need to compile a map file of the production environment yourself.

Install

Install the source-location command line utility globally with npm. Elevated privileges might be needed via sudo, depending on the platform. In most cases just:

npm install --global source-location

Command line options

The output of source-location --help pretty much covers all the options:

Usage: sl [options]

Options:
  -v, --version           output the version number
  -p, --source-flie-path  The generated source file
  -l, --ine               The line number in the generated source
  -c, --column            The column number in the generated source
  -h, --help              output usage information

Testing

use the following commands

sl -p dist/1.f47efcb58028826c7c05.js.map -l 1 -c 34 

output：

sourcecode info:
sourceCodePath: webpack:///src/pages/common/403.vue // 
line: 4
column: 15
name: export
