This avoids ninja unnecessarily rebuilding rust targets. Add a check for problems like these to be run on appveyor. |

A secure TypeScript runtime built on V8
-
Supports TypeScript 3.0.1 out of the box. Uses V8 6.9.297. 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 out/release/deno -rwxr-xr-x 1 rld staff 48M Aug 2 13:24 out/release/deno > otool -L out/release/deno out/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.
-
Supports top-level
await. -
Aims to be browser compatible.
Status
Under development.
The prototype golang implementation is here. We are in the process of rewriting in C++/Rust to avoid future GC contention between Go and V8.
Progress towards first release is tracked here.
Roadmap is here. Also see this presentation.
Build instructions
To ensure reproducable builds, Deno has most of its dependencies in a git submodule. However, you need rustc installed separately.
You probably want ccache installed too.
To build:
# Fetch deps.
git clone --recurse-submodules https://github.com/denoland/deno.git
cd deno
./tools/setup.py
# Build.
./tools/build.py
# Run
./out/debug/deno tests/002_hello.ts
Other useful commands:
# Call ninja manually.
./third_party/depot_tools/ninja -C out/debug :all
# Build a release binary.
DENO_BUILD_MODE=release ./tools/build.py :deno
# List executable targets.
./third_party/depot_tools/gn ls out/debug //:* --as=output --type=executable
# List build configuation.
./third_party/depot_tools/gn args out/debug/ --list
# Edit build configuration.
./third_party/depot_tools/gn args out/debug/
# Describe a target.
./third_party/depot_tools/gn desc out/debug/ :deno
./third_party/depot_tools/gn help
