@ -9,22 +9,28 @@ This module does not include a web interface so you need to open
`chrome://tracing/` in a Chrome browser and load the generated file to view the
result.
**Note:** You should not use this module until the `ready` event of the app
module is emitted.
```javascript
const {contentTracing} = require('electron')
const {app, contentTracing} = require('electron')
const options = {
categoryFilter: '*',
traceOptions: 'record-until-full,enable-sampling'
}
app.on('ready', () => {
const options = {
categoryFilter: '*',
traceOptions: 'record-until-full,enable-sampling'
}
contentTracing.startRecording(options, () => {
console.log('Tracing started')
contentTracing.startRecording(options, () => {
console.log('Tracing started')
setTimeout(() => {
contentTracing.stopRecording('', (path) => {
console.log('Tracing data recorded to ' + path)
})
}, 5000)
setTimeout(() => {
contentTracing.stopRecording('', (path) => {
console.log('Tracing data recorded to ' + path)
})
}, 5000)
})
})
