# gulp-dedupe [](https://travis-ci.org/hoho/gulp-dedupe)
|
||
|
|
|
||
|
|
Check for duplicates in the stream and filter them or throw an error.
|
||
|
|
|
||
|
|
|
||
|
|
Install:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm install gulp-dedupe --save-dev
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var dedupe = require('gulp-dedupe');
|
||
|
|
|
||
|
|
...
|
||
|
|
.pipe(dedupe()) // Remove duplicates from previous tasks (if any).
|
||
|
|
.pipe(concat('bundle.css')) // For example, we need to concat the result without duplicates.
|
||
|
|
.pipe(gulp.dest('./build'));
|
||
|
|
```
|
||
|
|
|
||
|
|
`dedupe(options)` optionally accepts `options` object. There are two options:
|
||
|
|
|
||
|
|
+ `error` to emit an error in case of duplicate (`false` by default).
|
||
|
|
+ `same` to emit an error in case duplicates have different contents (`true` by
|
||
|
|
default).
|
||
|
|
+ `diff` to supply duplicates with different contents error (`same: true`)
|
||
|
|
with actual diff (`false` by default).
