How can I build my project offline?

[anick3]

I use lume with the following plugins: esbuild, minify_html, multilanguage, sass, source_maps.

Is there a way to vendor (and if that's currently not possible,) to cache all dependencies locally, so I can build my project offline?

It currently says

when I switch off my internet connection.

Btw. I love lume - it's so much better than everything I used before! Thank you so much for your work!

Deno cache all dependencies locally, so they are requested only the first time and then use the local cache. It should be enought to run Lume offline.

There's also the deno vendor command to store all dependencies locally in a directory (https://deno.land/[email protected]/tools/vendor). The problem is it doesn't work with npm: specifiers yet (it's in the roadmap but I don't know if it will be implemented in the short term.

Lume had the lume vendor command that runs deno vendor internally with additional tweaks to make it work. But this was removed in lume 1.12.0 due problems with npm dependencies. If you really need this, you can downgrade to lume 1.11.4 and use it.

Hi, and thank you for the fast reponse!

I just tried it again - I ran deno task build and then I pulled out my network cable (:) ) and ran deno task build again. It says

$ deno task build
Task build deno task lume
Task lume echo "import 'lume/cli.ts'" | deno run --unstable -A -

My configuration is totally standard - exactly the same as the example described under https://lume.land/docs/overview/installation/.

Ok, it's because the minify_html plugin. It uses minify-html dependency (a wasm library) and it seems that wasm files are not cached by Deno. Can you try it without this plugin?

[anick3]

You are right, it works when I comment out the minify-html import and use lines! Thank you! I wonder, why I got that sass error the first time, though.
