cache option doesn't work in 11ty --dryrun

[murtuzaalisurti]

• run 11ty in dry mode (skips writing files)
• images are still processed even if cache duration is specified as 2w

still unclear if it actually re-fetches the files or just logs

eleventyConfig.addPlugin(eleventyImageTransformPlugin, {
        formats: ["avif", "webp", "png", "jpeg"],
        cacheOptions: {
            duration: "2w",
        },
    });

here's a workaround I used:

/** @param {(import("@11ty/eleventy").UserConfig)} eleventyConfig */
export default function (eleventyConfig) {
    const dryRun = process.argv.includes("--dryrun"); // this

    // ...
    eleventyConfig.addPlugin(eleventyImageTransformPlugin, {
        formats: ["avif", "webp", "png", "jpeg"],
        cacheOptions: {
            duration: "2w",
        },
        statsOnly: dryRun,
    });
}

detect if 11ty is running in dry mode or not using process args and use the statsOnly option of eleventy-image to skip file processing.
