Setting up a MEAN project from scratch is not easy. Fortunately, there are many generators which one can use. I did a little search and found this one:
I generated my project several times and it was always failing to load – displayed LOADING message on start.
Finally, I figured that when I ran install command as recommended:
npm install -g yo gulp-cli generator-angular-fullstack
it installed generator-angular-fullstack v5 alpha 4. I checked their web site and the latest release was 4.1.0, so I had to uninstall generator and install version 4.1.0. Once I did it everything worked. Now I can build my app.
