/**
|
|
* This is a mock Segment API meant to be run from the command line. It will start a server
|
|
* with the port specified, and respond with HTTP 200 to all requests. Any requests will be
|
|
* logged to the console, along with the parsed Segment events included in the request (if
|
|
* any)
|
|
*
|
|
* This can be used with the MetaMask extension by setting the `SEGMENT_HOST` environment
|
|
* variable or config entry when building MetaMask.
|
|
*
|
|
* For example, to build MetaMask for use with this mock Segment server, you could set the
|
|
* following values in `.metamaskrc` before building:
|
|
*
|
|
* SEGMENT_HOST='http://localhost:9090'
|
|
* SEGMENT_WRITE_KEY=FAKE
|
|
* SEGMENT_LEGACY_WRITE_KEY=FAKE
|
|
*
|
|
* Note that the Segment keys must also be set - otherwise the extension will not send any
|
|
* metric events.
