What to know before exploring

What it is

A modern runtime for JavaScript and TypeScript.

GitHub

Where it is used

  • Netlify — Netlify used Deno Subhosting to build and ship its edge functions product within weeks, choosing it over building their own solution on AWS Lambda. Source

What people are saying

I love Deno and I use this, but I really wish they would fix this dumb bug: https://github.com/denoland/deno/issues/16466

I'd like to highlight dprint [0]. It is not as opinionated as Prettier, and its AST-node-specific configuration is awesome [1]. Deno uses it under the hood for `deno fmt` (and switched from Prettier [2]), and the TypeScript team uses it for formatting their code base (switched from formatting by ESLint [3]).

Bash scripts tend to be used in situations where you want to edit them and not have to deal with a recompilation step, let alone a multi-GB compiler install. That seems like a deal-breaker to me. The best alternative I've found so far is Deno. It natively supports single file scripts with third party dependencies (this is a big issue with replacing Bash with Python). It uses an existing popular language (so now "learn our weird language" problem). Installation is very easy. The only real downside I've found is this stupid bug that they refused to fix: https://github.com/denoland/deno/issues/16466

In this case, they've also documented the remote connection protocol: "KV Connect" https://github.com/denoland/deno/tree/main/ext/kv#kv-connect I kicked the tires on this with a pure TS implementation of the protocol called kv-connect-kit that gives you the KV client api in any Javascript runtime (including Cloudflare workers, which does not have anything Deno namespace related) - github: https://github.com/skymethod/kv-connect-kit - npm: https://www.npmjs.com/package/kv-connect-kit - deno/x: https://deno.land/x/kv_connect_kit - demo: https://keyspace.deno.dev/ protocol seems to works as described on the tin, and it would be pretty straightforward to write another backend

Yes, sort of - on Deno Deploy the authentication doesn't come from a token in env vars, but from intrinsic security tickets baked into the Deno Deploy system. Also, it's a bit faster on first connect, because compared to KV connect we can skip the metadata exchange[1] because the information it provides is already present in Deno Deploy through other means. Both the backend service and frontend API (JS->KV) is the same though :) [1]: https://github.com/denoland/deno/blob/be1fc754a14683bf640b7b...

Does this change your mind at all? https://github.com/denoland/deno/blob/be1fc754a14683bf640b7b... It looks to me like they've documented the KV Connect protocol they invented to support this feature, in enough detail that anyone else could build an alternative backend for it. This has helped me feel completely OK with how they're handling this. They get an advantage in that they've already built an extremely robust proprietary backend, but I find that acceptable given the documented protocol.

I poked around with this a few months ago to figure out how it works locally. The answer is SQLite: https://til.simonwillison.net/deno/deno-kv I'm finding the business model aspect of Deno KV absolutely fascinating. const kv = await Deno.openKv(); That's a Deno core API. It works fine in the open source version of Deno using a local SQLite database file. But as soon as you deploy your application to their proprietary hosted service, that core API feature gets massively more powerful. It's no longer a SQLite database, it's now a globally distributed key/value store backed by FoundationDB, replicated around the world. It looks like they've extended that idea further with the latest version - you can now do this: export DENO_KV_ACCESS_TOKEN="personal access token" const kv = await Deno.openKv( "https://api.deno.com/
Read the rest
databases/your-database/connect", ); And your local code is now able to manipulate that remote FoundationDB database as well. I'm having trouble thinking of a precedent for this - an open source project that has a core API which is effectively a lead generator for their proprietary cloud service. I'm not entirely sure how I feel about it. I think I like it: open source projects need a business model, and the openKv() method is still a supported, useful part of the open source offering. Kind of fascinating pattern though. UPDATE: I just found this page of docs https://github.com/denoland/deno/blob/be1fc754a14683bf640b7b... - which describes the "KV Connect" protocol they are using. It looks like this evens the playing field, in that anyone could implement their own alternative backend to Deno Deploy if they wanted to. This firmly establishes me on the "I think this is cool" side of the fence.
