const AggregateError = require('aggregate-error'); const error = new AggregateError([new Error('foo'), 'bar', {message: 'baz'}]); throw error; /* AggregateError: Error: foo at Object.<anonymous> (/Users/sindresorhus/dev/aggregate-error/example.js:3:33) Error: bar at Object.<anonymous> (/Users/sindresorhus/dev/aggregate-error/example.js:3:13) Error: baz at Object.<anonymous> (/Users/sindresorhus/dev/aggregate-error/example.js:3:13) at AggregateError (/Users/sindresorhus/dev/aggregate-error/index.js:19:3) at Object.<anonymous> (/Users/sindresorhus/dev/aggregate-error/example.js:3:13) at Module._compile (module.js:556:32) at Object.Module._extensions..js (module.js:565:10) at Module.load (module.js:473:32) at tryModuleLoad (module.js:432:12) at Function.Module._load (module.js:424:3) at Module.runMain (module.js:590:10) at run (bootstrap_node.js:394:7) at startup (bootstrap_node.js:149:9) */ for (const individualError of error) { console.log(individualError); } //=> [Error: foo] //=> [Error: bar] //=> [Error: baz]
Returns an Error
that is also an Iterable
for the individual errors.
Type: Array<Error|Object|string>
If a string, a new Error
is created with the string as the error message.
If a non-Error object, a new Error
is created with all properties from the object copied over.
