Another (!!) etcd library for nodejs. This is formerly based on etcd-node, but has since evolved to a full-fledged new library with etcd v2 support.
This is not stable at the moment. Development will follow closely the development of etcd and changes in its API. minor-version changes will be kept in sync.
$ npm install nodejs-etcd
The client only need to be configured very simply by providing the base url of the etcd service.
var etcd = ;var e =url: ''
Nodejs-etcd supports the full v2 api specification.
Reads from etcd. All paths you may want to read start with '/' as the etcd hierarchy strictly mimics the one of a filesystem
All etcd flags are supported here as well; the valid options are:
recursive(boolean) it set to true, fetches all subdirectories
wait(boolean) if set to true, the request will wait until the value changes.
wait_index(integer) if set toghether with wait, will wait to return until the marked index is reached
The callback can be encapsulated using this method. It will return a valid callback for the other methods that will:
Let's say we just want to output the value of the key:
cb = ee
By default, if no callback is declared nodejs-etcd will log some important values of the response to the console.
Writes a key or dir to the cluster. Simplest form:
All etcd flags to a write operation are supported and must be added to the
prev_exists(boolean) key gets written only if it is being created.
prev_index(integer) sets the key only if the actual index is exactly this one.
prev_value(string) sets the key only if the actual value is this one.
Deletes a key from etcd. If the
recursive option is set to true, it will allow to remove directories.
