fastpack
Pack JS code into a single bundle fast & easy.
Motivation
The goal for fastpack is to provide fast and robust development time bundling for JavaScript applications which scales up to tens of thounsands of modules without sacrificing development experience.
We want sub-1000ms bundle time and sub-100ms incremental rebundle time for medium-sized applications (around 1000 modules). We are almost there.
Installation
You can install via npm (or yarn):
% npm install fpack
Usage
To produce a development bundle:
% fpack --development ./index.js
To produce a production bundle:
% fpack ./index.js \
--postprocess 'babel --presets env' \
--postprocess 'uglify -cm'
Note that babel
, babel-preset-env
and uglify-js
packages must be
installed.
Reference
Run fpack --help

NAME
fpack - Pack JavaScript code into a single bundle
SYNOPSIS
fpack [OPTION]... [ENTRY POINTS]...
ARGUMENTS
ENTRY POINTS
Entry points. Default: ['.']
OPTIONS
-d, --debug
Print debug output
--development
Build bundle for development
--help[=FMT] (default=auto)
Show this help in format FMT. The value FMT must be one of `auto',
`pager', `groff' or `plain'. With `auto', the format is `pager` or
`plain' whenever the TERM env var is `dumb' or undefined.
--mock=PACKAGE[:SUBSTITUTE]
Mock PACKAGE requests with SUBSTITUTE requests. If SUBSTITUTE is
omitted empty module is used.
-n NAME, --name=NAME (absent=index.js)
Output File Name. The target bundle filename will be NAME
--no-cache
Do not use cache at all (effective in development mode only)
--node-modules=PATH, --nm=PATH
Paths to 'node_modules' directory. Should be inside the project
directory.. Defaults to ['node_modules']
-o DIR, --output=DIR (absent=./bundle)
Output Directory. The target bundle will be DIR/index.js.
--postprocess=COMMAND
Apply shell command on a bundle file. The content of the bundle
will be sent to STDIN and STDOUT output will be collected. If
multiple commands are specified they will be applied in the order
of appearance
--preprocess=PATTERN:PROCESSOR?OPTIONS[!...]
Preprocess modules matching the PATTERN with the PROCESSOR.
Optionally, the processor may receive some OPTIONS in form:
'x=y&a=b'. There are 2 kinds of currently supported processors:
'builtin' and the Webpack loader. 'builtin' preprocessor provides
the following transpilers: stripping Flow types, object spread &
rest operators, class properties (including statics), class/method
decorators, and React-assumed JSX conversion. 'builtin' may be
skipped when setting this option, i.e. '\.js
