electron-har
A command-line tool for generating HTTP Archive (HAR) (based on Electron).
The data you get is identical to "Chromium -> Developer Tools -> Network pane -> Save All as HAR".
Installation
Prebuilt binaries can be found on the release(s) page.
You can also use npm:
npm install -g electron-har
In order for Electron to work on Debian/Ubuntu (specifically on Debian 8/Ubuntu 12.04) following packages have to be installed
libgtk2.0-0 libgconf-2-4 libasound2 libxtst6 libxss1 libnss3
.
Usage
NOTE for Linux users: you might need to --disable-gpu
# NOTE: on Linux --disable-gpu might be needed
electron-har http://google.com # writes HAR to stdout
# in case something doesn't look right / not working
ELECTRON_ENABLE_LOGGING=1 electron-har --disable-gpu --show http://google.com 2>electron.log
# in a headless environment (CI agent on Linux?) - xvfb-run will do just fine
DISPLAY=:1 xvfb-run electron-har http://google.com -o google_com.har
# to see a complete list of command line options
electron-har --help
... or pragmatically
const electronHAR = require('electron-har')
electronHAR('http://enterprise.com/self-destruct', {
user: {
name: 'jean_luc_picard',
password: 'picard_4_7_alpha_tango'
}
}, function (err, json) {
if (err) {
throw err
}
console.log(json.log.entries)
})
In a headless environment you might want to use kesla/headless (which will start Xvfb for you).
const headless = require('headless')
const electronHAR = require('electron-har')
(function (cb) {
if (!process.env.DISPLAY) {
headless(function (err, proc, display) {
if (err) {
return cb(err)
}
process.env.DISPLAY = ':' + display
cb(null, proc)
})
} else {
process.nextTick(cb)
}
})(function (err, xvfb) {
if (err) {
throw err
}
electronHAR(..., function (err, json) {
...
xvfb && xvfb.kill()
})
})
