Roadmap of 2021

[ije]

Roadmap List

• split internal bundle by the exports field in package.json (Relative imports shouldn't be bundled #78)
• support storage interface to save builds to everywhere over local fs(Support storage interface #76)
• nested deps should respect the ?deps parameter(v45 - nested dependency overrides have changed #101)
• use deno deploy as front layer
• preload deps
• transform ts/tsx/jsx for browsers from github

  import "https://esm.sh/~ije/ui/Button.tsx"  // Content-Type: application/javascript

@ije I have a local branch where I have basically taken an additive approach to the fs_local implementation (duplicated and layered onto fs_local), and added https://github.com/dgraph-io/ristretto as a gate keeper. Would you be interested?

[jimisaacs]

Take a look at that project if you can, it's an interesting approach:

High Hit Ratios - with our unique admission/eviction policy pairing, Ristretto's performance is best in class.
Eviction: SampledLFU - on par with exact LRU and better performance on Search and Database traces.
Admission: TinyLFU - extra performance with little memory overhead (12 bits per counter).

My implementation assumes a stateless container, so while still using your standard local fs, I just make the assumption that what ever is in the cache is the source of truth. Though even if it's not in a stateless container, I'd still almost like to just assume it is, and clear the local storage directory on server start 🤷

[jimisaacs]

What is in the cache is just a struct with the name and modtime.

@jimisaacs there are two different kind of LRUs i think, one is a FS storage that can remove the old(cold) files automatically since the build outputs take lot of storage space over time. the other one is a redis layer to map the request url to the entry JS, currently i only use the postdb(a embed db i created) to cache package versions.
