eslint-plugin-no-wildcard-postmessage
JSON →ESLint plugin that enforces a custom rule disallowing calls to `postMessage` with a wildcard target origin (`"*"`). Stable version 0.2.0, no frequent updates. This is a security-focused lint rule used internally at Mozilla to prevent unsafe cross-origin messaging; it only targets the `postMessage` API and is a lightweight, single-rule plugin.
