Rewrite the getChunkOptions function to not use
closure-calculate-chunks, but instead just chunk the input files
(more or less) by subdirectory: first chunk is core/, second is
blocks/, etc.
This does make a material change to blockly_compressed.js,
because we end up feeding several empty modules that contain
only typescript interface declarations and which tsc
compiles to "export {};" in the input to Closure Compiler
(closure-calculate-chunks is smart enough to notice that
no other module depends on these), which results in ~1.7KiB of
superflous
var module$build$src$core$interfaces$i_ast_node_location_svg={};
declarations. This can be avoided by filtering such empty modules
out but that has been left for a future commit.
This adds the glob NPM package as a dev dependency, but gulp
and several other existing dev dependencies already depend on
it.
Build time is sped up by about a factor of 3x, due to removal
of the buildDeps step that was really slow:
$ time npm run build
before:
real 0m24.410s
user 0m16.010s
sys 0m1.140s
after:
real 0m8.397s
user 0m11.976s
sys 0m0.694s
