path, opts): where path is the path on disk to save the file
to or the key to use for an alternative backend, such as etcd. Returns a new
sequence saving instance.<Promise> save.save(sequence): save the sequence to the configured backend.
Returns a Promise which will resolve once the value is saved.<Promise> save.read(): Returns a Promise that will resolve with the
current sequence #.To save sequence files to the filesystem, simply provide the following configuration:
const SeqSave = require('seq-save')
const seq = new SeqSave('my-sequence.seq', {
type: 'file'
})
It's worth noting that file is the default backend, so you can also
simply provide an empty configuration object..
To save sequence files to etcd, simply provide the following configuration:
const Save = require('seq-save')
const seq = new SeqSave('my-sequence.seq', {
type: 'etcd',
host: 'http://127.0.0.1:2379'
