## 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 `--reload` flag. (So, this will still work on an
|
|
airplane. See `~/.deno/src` for 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](https://github.com/denoland/deno/blob/master/src/msg.fbs). This makes it
|
|
easy to audit.
|
|
To enable write access explicitly use `--allow-write` and `--allow-net` for
|
|
network access.
|
|
|
|
* Single executable:
|
|
```

```
|
|
|
|
* Always dies on uncaught errors.
|
|
|
|
* Supports top-level `await`.
|
|
|
|
* Aims to be browser compatible.

## Status
|
|
|
|
Under development.
|
|
|
|
The prototype golang implementation is
|
|
[here](https://github.com/denoland/deno/tree/golang). 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](https://github.com/denoland/deno/issues?utf8=%E2%9C%93&q=is%3Aissue+milestone%3A%22v0.1+%28first+binary+release%29%22+).

## Build instructions
|
|
|
|
To ensure reproducable builds, Deno has most of its dependencies in a git
|
|
submodule. However, you need to install separately:
|
|
|
|
1. [Rust](https://www.rust-lang.org/en-US/install.html)
|
|
2. [Node](http://nodejs.org/)
|
|
3. Python 2. [Not 3](https://github.com/denoland/deno/issues/464#issuecomment-411795578).
|
|
4. [ccache](https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/ccache) (Optional but helpful for speeding up rebuilds of V8.)
|
|
.
|
|
|
|
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
|
|
# 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
|
|
|
|
Env vars: `DENO_BUILD_MODE`, `DENO_BUILD_PATH`, `DENO_BUILD_ARGS`.
