Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.

Advanced tools
A deep matching library.
matchDeep(value, source, options?)
import matchDeep from 'match-deep';
const matches = matchDeep(
{
a: 1,
b: 2
},
{
c: 1,
d: 2
},
{
shortCircuit: true
}
);
console.log(matches);
/*
{
result: false,
message: 'Number `1` and value `undefined` not equal for "c" ' +
'Number `2` and value `undefined` not equal for "d"',
errors: [
{
message: 'Number `1` and value `undefined` not equal',
keyPath: [Array]
},
{
message: 'Number `2` and value `undefined` not equal',
keyPath: [Array]
}
]
}
*/
Defaults:
{
shortCircuit: false,
skipKeys: [],
serializedRegex: false
}
shortCircuit
(boolean
) - true
will stop on the first match error and report only that one, which can help performance.
skipKeys
(string[]
) - an array of key names under which to not do comparisons - all keys are considered by default.
serializedRegex
(boolean
) - true
will interpret { $regex: { source: 'a.*b', flags: 'i' } }
as if it were /a.*b/i
.
This allows for serialization of regular expressions over JSON.
Also supports optional flags
as in { $regex: { source: 'a.*b' } }
, and just a source
string as in { $regex: 'a.*b' }
.
