Ts-morph: make it available for Deno

Describe the solution you'd like
Just make work this awesome lib for Deno

It would be great. ts-morph was actually previously used in Deno's build system when it was still on node.

ts-morph doesn't have too many dependencies, so I don't believe this would be too hard. I think probably the easiest solution here would be to build code-block-writer for Deno (has no dependencies), then bundle ts-morph and @ts-morph/common into a single file, then implement https://github.com/dsherret/ts-morph/blob/latest/packages/common/src/fileSystem/RealFileSystemHost.ts for Deno.

Opened https://github.com/dsherret/code-block-writer/issues/36

Edit: This is complete now.

One part about this was figuring out how to bundle the .d.ts files (aka lib files) for Deno. https://github.com/dsherret/ts-morph/pull/934 should solve this, but I think for Deno it will have to remove the "require" and always load the lib files module in getLibFiles()

https://github.com/dsherret/ts-morph/blob/3dd5c72a48a7a5852cf5f995126b8cc12567ee86/packages/common/src/getLibFiles.ts#L2-L5

ts-morph/common dependencies

• [x] TypeScript - Now bundled in ts-morph/common
• [x] is-negated-glob - Rewrite and include in ts-morph/common
• [x] dsherret/to-absolute-glob - Need to rewrite and include in ts-morph/common
• [x] mkdirp - Deno has a ensureDir at https://deno.land/[email protected]/fs/README.md
• [x] fast-glob - See expandGlob https://deno.land/[email protected]/fs
• [x] multimatch - Available from Deno https://deno.land/[email protected]/path/glob.ts

ts-morph dependencies

• [x] code-block-writer - Available for Deno https://github.com/dsherret/code-block-writer

Remaining Tasks

• [x] Create a Deno implementation of the Runtime interface.
• [x] Make a build for Deno. Can just be a single file.
• [ ] Add some code verification to enforce putting certain stuff in a Runtime and add some basic tests for Deno.

@hemedani this is now available here: https://deno.land/x/ts_morph

Note that I haven't developed a way to run the tests for the Deno module yet, so it might be a little bit unstable. I started using it in some of my Deno code in a different repo and seems to work well so far...
