Gulp and glob-stream task finishing too soon - gulp

Question

I have a Gulp task that uses glob-stream to recursively loop through directories and files to perform a task, similar to below, but far more elaborate:
var gs = require('glob-stream');
var config = {
PATH: 'some/path/*.*'
}
function doSomething(filePath) {
var stream = gs.create(filePath);
// Do something
return gs.on('data', doSomething);
}
gulp.task('compile', function() {
var filePath = config.PATH;
return doSomething(filePath);
});
I can have the task achieve the results and compile what I need, but unfortunately Gulp believes the task has finished while it's still running, causing issues in my build process - How can I avoid this? I'm already using run-sequence but to no effect.

Answer 1

Why are you manually walking the directory tree with a recursive function? Why not just let glob-stream do the work for you? Then you only have to take care of the //Do something part:
var config = {
PATH: 'some/path/**' //glob pattern for all subfolder and files
};
function doSomething(filePath) {
//Do something
}
gulp.task('compile', function() {
var stream = gs.create(config.PATH);
stream.on('data', doSomething);
return stream;
});
gulp.task('secondTask', function() {
console.log('secondTask');
});
gulp.task('default', function() {
runSequence('compile', 'secondTask');
});
The some/path/** glob pattern creates a stream of all folders and files below some/path/, so you don't have to implement the recursive tree walk yourself.
Note that the compile task returns the stream. Otherwise gulp can't tell when the compile task has completed and starts running secondTask before compile has finished.
