@canonical/jujulib - v2.0.0

JS Jujulib

This project provides a JavaScript API client library for interacting with the Juju WebSocket API.

Getting Started

In order to access the Juju API, a connection must be made, to either a Juju controller or model.

import ApplicationV5 from "jujulib/api/facades/application-v5.js";
import ClientV1 from "jujulib/api/facades/client-v1.js";
import ClientV2 from "jujulib/api/facades/client-v2.js";

const juju = await jujulib.connect(
  'wss://example.com/model/x-y-z/api',
  {facades: [ApplicationV5, ClientV1, ClientV2]}
);

In the code above, a connection is being established to the provided model API URL, and the client declares interest in using the specified set of facades.

Note When multiple versions of the same facade are included (like the two client versions in the example), the most recent version supported by the server is made available to the client.

The connect method returns a juju object which can be used to log into the controller or model by providing a userpass credentials or macaroons. See The various examples below.

Client API Reference

Visit the full API documentation for detailed information on the Client API.

Facade API Reference

Defailed Facade documentation can be found by visiting the full API documentation or you can visit the facade source directly using the links below.

Examples

We have a number of examples showing how to perform a few common tasks. Those can be found in the examples folder.

Library Maintenance

Updating Library Facades

The Juju facade API files are generated from a supplied Juju schema.

To generate this schema you will need to clone the Juju repository and then run go run github.com/juju/juju/generate/schemagen -admin-facades --facade-group=client,jimm ./apiserver/facades/schema.json to generate a schema file that contains the publicly available facades as well as the set of facades for JAAS. Other --facade-group options are latest and all.

To update the facades run npm run build on this project. This will generate the facades using the schema stored at $GOPATH/src/github.com/juju/juju/apiserver/facades/schema.json. It will also pull the SHA and Juju version from this repository.

Releasing to NPM

  • Update the version number in package.json, respecting semver.
  • Run the tests with npm test.
  • Run the examples with node to ensure that everything works as expected.
  • Upgrade the Juju Dashboard to this version using npm link and ensure that everything works as expected.
  • Tag the version in the git repository with the version number from above.
  • npm publish.
  • Update the release notes in the repository.
  • Create a post on the Juju Discourse with information about the release.
