CSP (Content-Security-Policy) Vite Plugin

Leverages csp-typed-directives to create typed CSP <meta> policies and validated interdependant headers. e.g. the CSP, CSP Report-Only, Report-To, and Referrer-Policy headers.

Mostly config compatible with csp-html-webpack-plugin

WARNING, STILL EARLY AND THINGS LIKE MODULE RESOLUTION ARE FINICKY

Now looking at making a multi-repo because this is going to require multiple layers of shared functionality and also built to an unplugin

Installation

Install the plugin with npm:

$ npm install --save-dev vite-plugin-csp
# Or shorthand
npm i -D vite-plugin-csp

Known issues

• Relative modules are resolved relative to the CWD, not the file
• no SSR support (and thus no nonce support)
• No parsing of JS embeded sources (since that would require framework specific plugins)
• Only script and style related directives are supported (except for the inclusion of report-to for generating headers)

Under construction :)
