/**
|
|
* Returns a middleware that implements the RPC methods defined in the handlers
|
|
* directory.
|
|
*
|
|
* The purpose of this middleware is to create portable RPC method
|
|
* implementations that are decoupled from the rest of our background
|
|
* architecture.
|
|
*
|
|
* Handlers consume functions that hook into the background, and only depend
|
|
* on their signatures, not e.g. controller internals.
|
|
*
|
|
* Eventually, we'll want to extract this middleware into its own package.
|
|
*
|
|
* @param {Object} opts - The middleware options
|
|
* @param {Function} opts.sendMetrics - A function for sending a metrics event
|
|
* @returns {(req: Object, res: Object, next: Function, end: Function) => void}
