Embedding Deno in a Rust App to evaluate dynamic javascript/typescript inputs/files?
Given deno is written in pure rust, can i embed deno as an internal javascript/typescript evaluator for a rust app. The use-case is having user submitted scripts to evaluate on a streaming input and collect response generate by the script against that input. having a dynamic script submitted as a javascript/typescript offers big flexibility for my system.

Roll your own JavaScript runtime
A walk-through of creating a CLI that executes JavaScript files.
so is there a example of enriching the runtime with most used APIs? or a full fledged nodejs like/compatible standard library?
or will have to hand-craft each based on the script using those methods and then patching it up?
Deno itself is the only example that has Node apis available
And can I embed deno in my rust app?
You'd have to fork Deno. We don't distribute it as a library
This use case have wide impact on deno adoption. Any plans to support this in near future?
You can use the
deno_runtime crate instead of raw deno_core it comes with standard Deno ops like: like fetch, Deno apis etc... you still need to hand craft the Typescript parser and the external import system like npm, esm etc... but its a good start point since already impl a loot of Js apis
You can also use the v8 crate direct to evaluate Js code directly from rust and combine it with the serde_v8 crate to I/O between rust and Js. All of this packages are re-exported by the deno_core crate as well the deno_runtimeGitHub
