feat: initial support for Deno

[kurtaking]

Summary

Migrate from Node to Deno.

Details

This PR migrates the CLI to leverage Deno. I could run things locally to update master -> main for a few of my older repositories. The discussion here inspired this PR and works to resolve #5.

Testing

• Verified it's working locally with both .js and .ts files.
• Ran scripts/script.js and scripts/script.ts against several of my older repos to update branch protection rules.

deno run -A cli.js -T $GITHUB_TOKEN -R '[repo-name]'

Remaining Tasks

• remove pr sample files (cli.js, script.ts)
• migrate package.json scripts (and more?) to deno.json
• find replacements for process.arch and process.platform

We sholudn't replace the Node CLI with Deno. The Deno CLI should be an addition and probably become the recommended way to run Octoherd scripts. But the Node version is used as dependencies in scripts today in order to run the script packages directly using npx: https://github.com/octoherd/script-hello-world/blob/dd5c0cfd6ebf93ff3348f48fc1f53329c646a1f5/package.json#L21

Hey @gr2m, I am cross-referencing your response here to consolidate the discussion.

I like the idea of having a separate repository and will continue to work on this if you like the direction. What's the next step in getting the repository set up?

edit: I'll set up the repository and we can talk about transferring at a later date.

yeah that's what I'd suggest as well, thank you!

[kurtaking]

I can run things locally, so making some progress. I am definitely not as comfortable with Deno as anticipated 😬 😅

I could use some help if anyone is interested.

[gr2m]

thanks for the update! It's always hard in the beginning when figuring things out. Thank you for staying on it

[kurtaking]

@gr2m, the issue faced now is around dynamic imports. The output of deno compile does not support dynamically importing files that were not present at compilation time [ref].

The output of deno install does not support dynamic imports.

[gr2m]

around dynamic imports

Try this:

const { script } = await import("https://esm.sh/@octoherd/script-hello-world")
// now call `script(octokit, repository, options)` for every repository

Replace @octoherd/script-hello-world with the script name. The Deno CLI binary could work the same as the current Node-based CLI in terms for CLI arguments, for example:

$ deno-octoherd run -S https://esm.sh/@octoherd/script-hello-world@3.0.0

[kurtaking]

@gr2m, I have things working now for scripts coming from a URL. I have not figured out how to handle the failures for local files yet. I'm at a stopping point for today, but this feels good.

when importing locally, make sure to either use a relative path starting with ./, like ./examples/script.ts
