Lints against harmful usage of Atlassian's web APIs, the scope of which currently extends to its REST APIs and JS API.
The plugin is available on the npm registry under the same package name: eslint-plugin-atlassian-webapis
ESLint is listed as a peer dependency.
Note that, as with other ESLint plugins, rules are prefixed with the plugin name (sans the eslint-plugin- prefix) as a form of namespacing. For example, to enable the no-unstable-api rule, you'd need to target atlassian-webapis/no-unstable-api in your config.
At present, this plugin provides one rule:
no-unstable-api: Disallow usage of unstable APIs.
