Any plan to be compatible with Deno?

[ghost]

This is a feature request.
Do you have any plan to become typescript compatible with Deno?

Using pika.dev version of Mongoose will work?
pkg.fyi/npm:mongoose

Thanks!

[vkarpov15]

Haven't tried with either Deno or Pika. Will test it out and see if there's anything blocking us.

Did anybody managed to use mongoose with deno?

I get a mongoose.connect is not a function

[vkarpov15]

Haven't tried it yet. Will try out Deno over the weekend and evaluate how much work it would be for us to support it.

[vkarpov15]

I took a look at Deno and unfortunately we're currently blocked. Here's what's happening:

1. Do not use pika.dev's distribution of Mongoose. For some reason, they're pulling the browser version of Mongoose. So you won't be able to connect to MongoDB with Pika's version.

2. Deno currently bugs out with the require_optional npm module, which is something that the MongoDB driver uses internally.

3. Even without require_optional, Deno currently doesn't have a polyfill for Node's crypto module: https://deno.land/std/node/README.md . That's going to be hard for the MongoDB driver to work around.

Here's the Deno script I was working with:

import { createRequire } from "https://deno.land/std/node/module.ts";

const require = createRequire(import.meta.url);

const mongoose = require('mongoose');

console.log(mongoose.version);

Anybody know of a good workaround for using crypto in deno?

Anyone tried god crypto module?

Also MongoDB is available on deno platform:

https://deno.land/x/[email protected]

[ebebbington]

@luckycreationsindia but deno_mongo is a deno plugin, thus very unstable

Yes, MongoDB is available on deno platform, but there is very limited database features.

Deno 1.15 also crypto api updates

Ehm we need Deno support.

I wanna repeat the OP's question:

[vkarpov15]

@learner00000 not currently.

Deno will be compatible with mongoose, before they do anything xD (deno compact mode)

[Uzlopak]

It seems, that deno can now load mongoose when using the --unstable flag.

import { createRequire } from "https://deno.land/std/node/module.ts";

const require = createRequire(import.meta.url);

const mongoose = require('mongoose');

console.log(mongoose.version);

with unstable flag

Note: There is still no Deno-first code.

[Uzlopak]

Note: will be part of the next minor release.

Oh.
