A secure TypeScript runtime built on V8
-
Supports TypeScript 3.1 out of the box. Uses V8 7.1. That is, it's very modern JavaScript.
-
No
package.json. No npm. Not explicitly compatible with Node. -
Imports reference source code URLs only.
import { test } from "https://unpkg.com/deno_testing@0.0.5/testing.ts"; import { log } from "./util.ts";Remote code is fetched and cached on first execution, and never updated until the code is run with the
--reloadflag. (So, this will still work on an airplane. See~/.deno/srcfor details on the cache.) -
File system and network access can be controlled in order to run sandboxed code. Defaults to read-only file system access and no network access. Access between V8 (unprivileged) and Rust (privileged) is only done via serialized messages defined in this flatbuffer. This makes it easy to audit. To enable write access explicitly use
--allow-writeand--allow-netfor network access. -
Single executable:
> ls -lh target/release/deno -rwxr-xr-x 1 rld staff 48M Aug 2 13:24 target/release/deno > otool -L target/release/deno target/release/deno: /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.50.4) /usr/lib/libresolv.9.dylib (compatibility version 1.0.0, current version 1.0.0) /System/Library/Frameworks/Security.framework/Versions/A/Security (compatibility version 1.0.0, current version 58286.51.6) /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.0) > -
Always dies on uncaught errors.
-
Aims to be browser compatible.
