The easiest way of running code in a browser environment.
Bundles electronjs
by default!
$ echo "console.log('Hey from ' + location); window.close()" | browser-run
Hey from http://localhost:53227/
$
Or use browser-run
programmatically:
var run = require('browser-run');
var browser = run();
browser.pipe(process.stdout);
browser.end('console.log(location); window.close()');
$ browserify main.js | browser-run
or
var browserify = require('browserify');
var browser = require('browser-run');
browserify('main.js').bundle().pipe(browser()).pipe(process.stdout);
$ browser-run --help
Run JavaScript in a browser.
Write code to stdin and receive console output on stdout.
Usage: browser-run [OPTIONS]
Options:
--browser, -b Browser to use. Always available: electron. Available if installed: chrome, firefox, ie, phantom, safari [default: "electron"]
--port Starts listening on that port and waits for you to open a browser
--static Serve static assets from this directory
--input Input type. Defaults to 'javascript', can be set to 'html'.
--help Print help
By using -input html
or { input: 'html' }
you can provide a custom html file for browser-run to use. Keep in mind though that it always needs to have <script src="/reporter.js"></script>
above other script tags so browser-run is able to properly forward your console.log
s etc to the terminal.
Returns a duplex stream and starts a webserver.
opts
can be:
port
: If speficied, no browser will be started, so you can point one yourself tohttp://localhost/<port>
browser
: Browser to use. Defaults toelectron
. Available if installed:chrome
firefox
ie
phantom
safari
static
: Serve static files from this directoryinput
: Input type. Defaults tojavascript
, can be set tohtml
.
If only an empty string is written to it, an error will be thrown as there is nothing to execute.
If you call window.close()
inside the script, the browser will exit.
Stop the underlying webserver.
To use the default electron browser on travis, add this to your travis.yml:
addons:
apt:
packages:
- xvfb
install:
- export DISPLAY=':99.0'
- Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
- npm install
For gnu/linux installations without a graphical environment:
$ sudo apt-get install xvfb # or equivalent
$ export DISPLAY=':99.0'
$ Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
$ browser-run ...
There is also an example docker machine here.
With npm do
$ npm install browser-run # for library
$ npm install -g browser-run # for cli
