Minifiying the js code was taking too much time. Minifying is not
really needed on developer's machine, so lets disable it by
default, otherwise it gets annoying during development having to
wait for so many seconds for it to build.
A simple 'make' now means no debug-info and non-minified
bundle.js. To add debug-info(source-maps), do 'make DEBUG=true'.
And to minify, similarly use the MINIFY=true variable with make.
'make dist' forcefully minifies the js code.
This should give more fine-grained control as now we are sure
what version of browserify, or any other tool we are using to bundle
our assets. Installing browserify globally is also not required now.
This will also be helpful when we add more complicated transforms
and other tools to our build process, as otherwise it would keep
complicating our command used currently for the build process.
Till now we have only been linting our src/ directory. toolbar.js
is the only file we edit directly in dist/. Lets keep a check on
it too.
