I have a function I use in my gulp setup that looks something like:
// browserified - the result of browserify(...)
x = function(browserified, entryScriptPath){
// Promise is bluebird
return new Promise(function(resolve, reject){
var basename = path.basename(entryScriptPath, path.extname(entryScriptPath)) + '.js';
browserified.bundle()
.pipe(source(basename)) // vinyl-source-stream
.pipe(buffer()) // vinyl-buffer
.pipe(aGulpPlugin())
.pipe(anotherGulpPlugin())
//...
.on('error', reject)
.on('finish', resolve);
});
}
An error was occurring while bundling but I got no textual error or stackerror, it just exited eventually with the wrong code. So I found this:
Return a readable stream with the javascript file contents or optionally specify a cb(err, buf) to get the buffered results.
I passed a callback like browserified.bundle(function(err){ if(err) reject(err); }) which worked fine when there was an error but that now breaks everything else when there isn't an error because the docs say you can either get a stream or a buffer but not both.
Is there a way I can grab this error another way and still keep my code? Or if not, I know I could move a lot of my stream stuff inside that callback but sorry I'm no stream expert and am unsure how to get that buffer into a vinyl transform stream which suits the gulp plugins. Like:
browserified.bundle(function(err, buf){
if(err) return reject(err);
// ????
// something with buf
// ????
.pipe(aGulpPlugin())
.pipe(anotherGulpPlugin())
// ...
});
