Package Exports

@datadog/browser-logs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@datadog/browser-logs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Setup

NPM

import { datadogLogs } from '@datadog/browser-logs'
datadogLogs.init({
  clientToken: 'XXX',
  datacenter: 'us',
  forwardErrorsToLogs: true,
  sampleRate: 100
})

Bundle

<script src = 'https://www.datadoghq-browser-agent.com/datadog-logs-us.js'>
<script>
    window.DD_LOGS.init({
        clientToken: 'XXX',
        datacenter: 'us',
        forwardErrorsToLogs: true,
        sampleRate: 100
    });
</script>

Public API

What we call Context is a map {key: value} that will be added to the message context.

Init must be called before other methods. Configurable options:
- isCollectingError: when truthy, we'll automatically forward console.error logs, uncaught exceptions and network errors.
- sampleRate: percentage of sessions to track. Only tracked sessions send logs.
- datacenter: defined to which datacenter we'll send collected data ('us' | 'eu')
```
init(configuration: {
    clientToken: string,
    datacenter?: string,
    isCollectingError?: boolean,
    sampleRate?: number
})
```

Default logger

logger.debug | info | warn | error (message: string, messageContext = Context)`
logger.log (message: string, messageContext: Context, status? = 'debug' | 'info' | 'warn' | 'error')
logger.setLevel (level?: 'debug' | 'info' | 'warn' | 'error')
logger.setHandler (handler?: 'http' | 'console' | 'silent')
logger.addContext (key: string, value: any)  # add one key-value to the logger context
logger.setContext (context: Context)  # entirely replace the logger context

Custom loggers

Custom loggers have the same API than the default logger

createLogger (name: string, conf?: {
    level?: 'debug' | 'info' | 'warn' | 'error'
    handler?: 'http' | 'console' | 'silent'
    context?: Context
})  # create a new logger
getLogger (name: string)  # retrieve a previously created logger

Modify the global context for all loggers

addLoggerGlobalContext (key: string, value: any)  # add one key-value to the default context
setLoggerGlobalContext (context: Context)  # entirely replace the default context
