Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Readme
This library accepts a code location (in the form of a StackFrame) and returns a new StackFrame with a more accurate location (using source maps) and guessed function names.
This is primarily a browser-centric library, but can be used with node.js. See the Offline Usage section below.
var stackframe = new StackFrame({fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284});
var callback = function myCallback(foundFunctionName) { console.log(foundFunctionName); };
// Such meta. Wow
var errback = function myErrback(error) { console.log(StackTrace.fromError(error)); };
var gps = new StackTraceGPS();
// Pinpoint actual function name and source-mapped location
gps.pinpoint(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Better location/name information from source maps
gps.getMappedLocation(stackframe).then(callback, errback);
//===> Promise(StackFrame({fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Get function name from location information
gps.findFunctionName(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284}), Error)
With a bit of preparation, you can use this library offline in any environment. Any encountered fileNames not in the cache return resolved Promises with the original StackFrame. StackTraceGPS will make a best effort to provide as good of response with what is given and will fallback to the original StackFrame if nothing better could be found.
var stack = ErrorStackParser.parse(new Error('boom'));
console.assert(stack[0] == new StackFrame({fileName: 'http://localhost:9999/file.min.js', lineNumber: 1, columnNumber: 32}));
var sourceCache = {'http://localhost:9999/file.min.js': 'var foo=function(){};function bar(){}var baz=eval("XXX");\n//# sourceMappingURL=file.js.map'};
var sourceMap = '{"version":3,"sources":["./file.js"],"sourceRoot":"http://localhost:4000/","names":["foo","bar","baz","eval"],"mappings":"AAAA,GAAIA,KAAM,YACV,SAASC,QACT,GAAIC,KAAMC,KAAK","file":"file.min.js"}';
var sourceMapConsumerCache = {'http://localhost:4000/file.js.map': new SourceMap.SourceMapConsumer(sourceMap)};
var gps = new StackTraceGPS({offline: true, sourceCache: sourceCache, sourceMapConsumerCache: sourceMapConsumerCache});
gps.pinpoint(stack[0]).then(function(betterStackFrame) {
console.assert(betterStackFrame === new StackFrame({functionName: 'bar', fileName: 'http://localhost:9999/file.js', lineNumber: 2, columnNumber: 9}));
});

to prevent all network requests.pinpoint(stackframe)
=> Promise(StackFrame)Enhance function name and use source maps to produce a better StackFrame.
.findFunctionName(stackframe)
=> Promise(StackFrame)Enhance function name and use source maps to produce a better StackFrame.
.getMappedLocation(stackframe)
=> Promise(StackFrame)Enhance function name and use source maps to produce a better StackFrame.
Functions that rely on Source Maps
(pinpoint
and getMappedLocation
) require recent browsers.
