passError
|
||
|
|
=========
|
||
|
|
|
||
|
|
Handle success and failure with two different callbacks. Lets you get
|
||
|
|
rid of most `if (err) return cb(err);` constructs.
|
||
|
|
|
||
|
|
|
||
|
|
Example
|
||
|
|
-------
|
||
|
|
|
||
|
|
Send errors reported by `fs.readFile` straight to `cb`:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var passError = require('passerror'),
|
||
|
|
fs = require('fs');
|
||
|
|
|
||
|
|
function getLines(fileName, cb) {
|
||
|
|
fs.readFile(fileName, 'utf-8', passError(cb, function (contents) {
|
||
|
|
cb(null, contents.split(/\r?\n|\n?\r/));
|
||
|
|
}));
|
||
|
|
}
|
||
|
|
```
