asset-squisher is a Docker container and application to ease the compression of static assets, such as scripts and images. It's super easy to use!
FROM ghcr.io/randomairborne/asset-squisher AS compressor
COPY /your-app/dist/ /your-app/raw-dist/
RUN asset-squisher /your-app/raw-dist/ /your-app/static/
FROM alpine:latest
COPY --from=built /executables/your-app /usr/bin/
COPY --from=compressor /your-app/static/ /var/www/your-app-static/
CMD ["/usr/bin/your-app"]This example assumes your app will serve static files from
/var/www/your-app-static/. It will change all image files
to png, jpeg, webp, and avif, as well as copying the
original image files. Generic files, like JavaScript files,
are copied into the new directory, along with .br (brotli),
.gz (gzip), .zz (deflate), and .zst (zstandard) variants which
are used by some web servers for precompression. For example,
if my input included analytics.js, files would be created for
analytics.js, analytics.js.br, analytics.js.gz, and so on.
