Deprecate Google Analytics Integration

Problem

TypeDoc supports specifying a gaId option. When set, this causes TypeDoc to include Google Analytics tracking code in the generated pages. This causes a problem for anyone attempting to comply with the EU Cookie Law as TypeDoc does not generate a cookie banner.

Suggested Solution

Push the gaId option to an external plugin. I could generate a cookie banner within TypeDoc, but other plugins (like typedoc-clarity-plugin) also ought to cause this to be generated, so TypeDoc's check would have to be externally controlled.

Are you aware of any google analytics plugin? I would like to migrate

One can be easily constructed from the code in 1b55285

$ typedoc --plugin ./analytics.mjs

// @ts-check
// Apache License 2.0 - https://github.com/TypeStrong/typedoc/blob/master/LICENSE
import td from "typedoc";

/** @param {td.Application} app */
export function load(app) {
    app.options.addDeclaration({
        name: "gaID",
        help: "Set the Google Analytics tracking ID and activate tracking code",
        type: td.ParameterType.String,
    });

    app.renderer.hooks.on("body.end", () => {
        const gaID = app.options.getValue("gaID");
        if (gaID) {
            const script = `
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', '${gaID}');
`.trim();
            return td.JSX.createElement(td.JSX.Fragment, null, [
                td.JSX.createElement("script", {
                    async: true,
                    src: "https://www.googletagmanager.com/gtag/js?id=" + gaID,
                }),
                td.JSX.createElement("script", null, td.JSX.createElement(td.JSX.Raw, { html: script })),
            ]);
        }
        return td.JSX.createElement(td.JSX.Fragment, null);
    });
}

I think in the official docs website, gaId is still specified as a possible option

Fixed with TypeStrong/typedoc-site@c43e28b, thanks
