Express Useful StackTrace
This module is used to a usefull stacktrace from an error thrown from an express middleware or controller
exemple:
declaration :
function getUsefulStacktrace(trace, separator = 'at newFn');
import getUsefulStacktrace from 'express-useful-stacktrace';
function errorHandlingMiddleware(err, req, res, next) {
const usefulStack = getUsefulStacktrace(err.stack);
}
err.stack ->
"Error
at new Error (/usr/errors.js:15:1)
at /usr/middlewares/myMiddleware.js:42:11"
usefulStack ->
[ ' at /usr/middlewares/myMiddleware.js:42:11' ]
err.stack ->
