当node脱离v8_deno：使用V8和Go实现的安全TypeScript运行时，下一代Node.js

deno

A JavaScript runtime using V8 6.8 and Go.

Supports TypeScript 2.8 out of the box.

No package.json, no npm. Not backwards compatible with Node.

Imports reference source code URLs only. import { test } from "https://unpkg.com/[email protected]/testing.ts"

import { log } from "./util.ts"

File system and network access can be controlled in order to run sandboxed code. Defaults to read-only file system access. Access between V8 (unprivileged) and Golang (privileged) is only done via serialized messages defined in this protobuf: https://github.com/ry/deno/blob/master/msg.proto This makes it easy to audit.

/lib64/ld-linux-x86-64.so.2 (0x00007f104fc64000)

Always dies on uncaught errors.

Supports top-level await.

Aims to be browser compatible.

Can be used as a library to easily build your own JavaScript runtime. https://github.com/ry/deno/blob/master/cmd/main.go

Status

Segfaulty.

Compile instructions

I will release binaries at some point but for now you have to build it yourself.

You need Protobuf 3. On Linux this might work:

cd ~

wget https://github.com/google/protobuf/releases/download/v3.1.0/protoc-3.1.0-linux-x86_64.zip

unzip protoc-3.1.0-linux-x86_64.zip

export PATH=$HOME/bin:$PATH

Then you need protoc-gen-go and go-bindata and other deps:

go get -u github.com/golang/protobuf/protoc-gen-go

go get -u github.com/jteeuwen/go-bindata/...

go get -u ./...

Installing v8worker2 is time consuming, because it requires building V8. It may take about 30 minutes:

go get -u github.com/ry/v8worker2

cd $GOPATH/src/github.com/ry/v8worker2

./build.py --use_ccache

You might also need Node and Yarn.

Finally the dependencies are installed.

Now you can build deno and run it:

> make

[redacted]

> ./deno testdata/001_hello.js

Hello World

>

make commands

make deno # Builds the deno executable

make test # Runs the tests.

make fmt # Formats the code.

make clean # Cleans the build.
