API

promptOnce(cacheFile, valueName)

• cacheFile (string): location of the cache file.
• valueName (string): name of value that will be displayed in the terminal when prompting the user.
• Returns a thenable (i.e. has a "then" method) event emitter. It promises the value event. value event notifies the value retrieval, error event notifies any error that occurs during retrieval or when caching the value after its retrieval (.then may resolve successfully but an I/O error could still happen afterwards), cache event notifies successful caching.
