Bundling nessie and running it doesn't work

[leabstrait]

I want to run Nessie with a shorter command than to type out the whole URL. So I opted for this 'bundling' solution as pointed out in the discord server of deno. However, I have a problem.

➜ deno bundle https://deno.land/x/nessie/cli.ts deps/nessie_cli.ts

Emitting bundle to "deps/nessie_cli.ts"
1450193 bytes emitted.

[Okay, bundling is done]

➜ deno run --allow-net --allow-read --allow-write https://deno.land/x/nessie/cli.ts make initialize_db

Created migration 1589728502895-initialize_db.ts at /home/***/***/migrations

[Migration gets created when running from a remote URL]

➜ deno run --allow-net --allow-read --allow-write deps/nessie.ts make initialize_db

[However, this does nothing]

Hi @leabstrait ! Thanks for letting me know of this! I haven't tried to bundle it until now, but I can see it being a useful feature. I will add it to the roadmap of v1. I will probably not deal with it until the rest of the functionalities are implemented, but it will be on the list 💪

Hi @leabstrait ! I think bundling finally works with Deno 1.0.5 and with Nessie 0.5.2 🎉 Can you confirm this?
deno bundle https://deno.land/x/[email protected]/cli.ts nessie_cli.js
deno run --allow-net --allow-read --allow-write nessie_cli.js init

Hi @halvardssm,

Yes it works @v0.5.2

Also, the bundle is a .js file, I see. I was trying to bundle it to .ts extension at first, but while running it, there were errors about typing. I changed it to .js and it worked promptly. Not a problem for me, just an observation.

I came to this problem when thinking of a solution like python virtualenvs which let you use specific versions of packages for one project. Since deno install did a global install, I had wanted something project-local.

Your fix of bundling solved this issue. But as I spend more time with deno, I don't know if python's virtualenv solution applies here, especially when you can specify versions in the URL itself and use a deps.ts to manage project dependencies.

Anyways great, thanks. You can close this issue as you see fit.

Great! deno bundle bundles the code into ESM JS so that it can run without the tsc overlay, I dont think bundling to TS will be supported anytime soon 🤔 Technically you can achieve what you want, but you will have to bundle each and every external module manually, and also get the types separately. I would probably use deps.ts for now and maybe move over to import maps when this is stable 💪
