Yasnippet Tutorial

My firsts steps with yasnippet

Thanks go to Jake B. for his comprehensive video about Yasnippet.
This tutorial is what I grab from that excellent video.
Install yasnippet with 
M-x package-install
Then enter 
yasnippet
Configure yasnippet: 
(use-package yasnippet
  :config
  (setq yas-snippet-dirs '("~/.emacs.d/mysnippets"))
  (yas-global-mode 1))
Create a new snippet: 
M-x yas-new-snippet
Save it under the yas-snippet-dirs sub-directory corresponding to the mode you want it to apply: if the snippet is for php-mode, then save it under 
~/.emacs.d/mysnippets/php-mode/

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin.

This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&
