@serveside/check-source-map
npx @serveside/check-source-map <sourcemap-filename> -l <line-number> -c <column-number>
Local sourcemap file
Read a sourcemap file given a line number and column number and return the line/column of the same in the source code:
For example:
$ npx @serveside/check-source-map ~/dist/prod.b6e7359deed79be25536.js.map -l 2 -c 106543
{
source: 'webpack://my-project/node_modules/some-module/some-file.js',
line: 158,
column: 52,
name: 'someMethodName'
}
Remote sourcemap file
Add the -r
flag to the command
For example:
$ npx @serveside/check-source-map https://some-website.example.com/js/prod.b6e7359deed79be25536.js.map -l 2 -c 106543 -r
{
source: 'webpack://my-project/node_modules/some-module/some-file.js',
line: 158,
column: 52,
name: 'someMethodName'
}
Using global npm module
Run:
npm i -g @serveside/check-source-map
Then can run s-csm
instead of npx @serveside/check-source-map
This module can also be used programatically:
const csm = require('@serveside/check-source-map');
async function someMethod() {
const result = await csm.readLocalSourcemap({
source: './some_local_map.js.map',
line: 1,
column 134
});
console.log(result);
}
The result
would be the same values that are echoed out by the cli.
Can also run with the same parameters for csm.readRemoteSourcemap
.
