it always rerun all gulp task when watch trigger server.run

it always rerun all gulp task when watch trigger server.run.

I use the sample gulpfile.js in the readme.

Also running into this. It's blocking me from using gulp-express, as I have other gulp tasks that deploy my app to production that should not be run. They are currently getting run when server.run is called.

Any way I can help with this fix?

Same problem I encountered. Here is the workaround:

// start the server in an independent task:
gulp.task('express-run', function () {
    server.run({
        file: 'app.js'
    });
});

// and then use this:
gulp.watch(['app.js', 'routes/**/*.js'], ['express-run']);

// instead of:
// gulp.watch(['app.js', 'routes/**/*.js'], [server.run]);

Merged the change, I assume this was fixed.

@gimm Unfortunately not. I still experience this issue (and another user as well: https://github.com/gimm/gulp-express/issues/18). cc @thiagomata

Note: I have performed npm update gulp-express and manually checked that I have the latest version of your package.

I’m happy to report that I’ve managed to make it work correctly. Here is an excerpt of my gulpfile:

var gulp = require('gulp');
var server = require('gulp-express');
var livereload = require('gulp-livereload');
// etc.

gulp.task('server', function () {
    server.run({ port: 35730 });

    gulp.watch('source/styl/*.styl', ['build-css']);
    gulp.watch(['app.js', 'routes/*.js'], function (e) {
        server.run({ port: 35730 });
        livereload.changed(e.path);
    });
});

gulp.task('build-css', function () {
    return gulp.src('source/styl/*.styl')
        .pipe(stylus({ compress: false, 'include css': true }))
        // other tasks
        .pipe(gulp.dest('public/css/'))
        .pipe(livereload());
});

I don’t know why switching from [server.run] to function () { server.run() } fixes the issue for me.

A note regarding my use of gulp-livereload: I’m using this plugin to manually handle refresh in the browser. I’m doing this because server.notify cannot be nicely integrated into .watch() arguments when there are other tasks listed (['build-css'] in my code). There is the workaround with using a callback function (described in the README of this repo) which I haven’t tried, but that code pattern does not seem optimal, so I’ve decided to run a custom livereload server using gulp-livereload. Notice how it can be easily hooked up to my "build-css" task by simply piping it at the end (.pipe(livereload())). It would be great if server.notify supported an analogous approach.
