Install with npm:
npm install karma-browserifast
"browserify" to your list of frameworks in
Any tests or other files to browserify should not be listed in Karma's
configuration. Instead, use the
browserify key. This accepts the same list as
files, e.g. filenames as strings, and/or objects with
// Files that are to be loaded as globalsfiles:"node_modules/es5-shim/es5-shim.js"// Files to browserifybrowserify:files:"test/**/*.js"pattern: "integration/**/*.js"watched: false
The last step is a temporary hack that we hope to get rid of very soon:
What is this? karma-browserifast works by adding a file to Karma's list of
files. This file resides in your OS tmp directory, and if you set the log level
karma.LOG_DEBUG, karma-browserifast will tell you the exact file name. This
file is empty, and the above pre-processor provides the content Karma will use.
The reason for this somewhat elaborate approach is that Karma's
does not wait for asynchronous operations, meaning we can't browserify in this
hook. The pre-processors however, are asynchronous, thus this hack. We're
investigating how to fix this weirdness.
Adds sourcemaps to your Browserify bundle.
When you move files from Karma's list of files to the browserify list, you also
opt out of Karma's watching feature. Don't worry, karma-browserifast has your
back. It tells Karma to watch its bundle, and updates this whenever
your files change. The Karma
autoWatch configuration option, as well as
individual files configurations (e.g.
watch: true|false), are respected. If
true, dependencies resolved by browserify will be watched in
addition to files explicitly enumerated.
There's also karma-browserify,
however, we found its performance to be unacceptable as the number of files in
our project increases. karma-browserify adds a pre-processor that browserifies
all known files each time a new file is passed to it. This means that for
files, karma-browserify will run
n! times and write to the same
n times. This quickly becomes noticably slow.
