### Usage
|
|
|
|
|
|
|
|
|
|
```typescript
|
2018-01-29 22:30:09 +00:00
|
|
|
import gulp = require('gulp');
|
2018-12-09 00:19:01 +00:00
|
|
|
import gulpFunction from 'gulp-function'; // default ES6 export
|
2018-01-29 22:28:03 +00:00
|
|
|
// import {forFirst, forEach, atEnd} from 'gulp-function'
|
|
|
|
|
|
|
|
|
|
let myAsyncFunction = async (file, enc) => {
|
|
|
|
|
// await some async stuff
|
|
|
|
|
};
|
|
|
|
|
|
2018-12-09 00:19:01 +00:00

gulp.task('gulpTest', function() {
|
2018-01-29 22:28:03 +00:00
|
|
|
let stream = gulp
|
2018-12-09 00:19:01 +00:00
|
|
|
.src('./mydir/*.something')
|
|
|
|
|
.pipe(gulpFunction(myAsyncFunction, 'forEach')) //read the notes below
|
2018-12-08 18:57:10 +00:00
|
|
|
// .pipe(forEach(myAsyncFunction)) // if imported as >> import { forEach } from 'gulp-function' <<
|
2018-12-09 00:19:01 +00:00
|
|
|
.pipe(gulp.dest('./build/'));
|
2018-01-29 22:28:03 +00:00
|
|
|
return stream; // by returning the stream gulp knows when our task has finished.
|
|
|
|
|
});
|
|
|
|
|
```

### Notes
|
|
|
|
|
|
2018-12-09 00:19:01 +00:00
|
|
|
- The first argument of gulpFunction can also be an **array of multiple functionnames**.
|
2018-01-29 22:28:03 +00:00
|
|
|
Each function can return a promise. The pipe stop will finish when every promise is fullfilled.
|
|
|
|
|
When providing an array of functions be careful with modifying the file object -> race condition
|
2018-12-09 00:19:01 +00:00
|
|
|
- The second argument can be empty, it defaults to "forEach"
|
|
|
|
|
- The following options are available:
|
|
|
|
|
- "forFirst" - executes when first chunk/vinylfile of the stream reaches the pipestop.
|
2018-01-29 22:28:03 +00:00
|
|
|
file is pushed further down the line when function's returned promise is fullfilled.
|
2018-12-09 00:19:01 +00:00
|
|
|
- "forEach" - executes like "forFirst" but with every chunk/vinylfile in the stream;
|
|
|
|
|
- "atEnd" - executes after all chunks have passed and are processed in full.
|
2018-01-29 22:28:03 +00:00
|
|
|
That means the stream's "finish" event fires **before "atLast" is executed**!!!
