graalvm 23.1.0 独立nodejs docker 镜像&简单试用

graaljs docker 镜像

很简单就是下载官方包，集成下，然后进行一些简单的配置

• Dockerfile

FROM debian:bullseye-backports

LABEL author="rongfengliang"

LABEL email="1141591465@qq.com"

WORKDIR /opt/

RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \

    && echo 'Asia/Shanghai' >/etc/timezone

COPY graalnodejs-23.1.0-linux-amd64/ /opt/nodejs/

ENV PATH=/opt/nodejs/bin:$PATH

参考项目

• package.json

{

  "name": "graaljs-learning",

  "version": "1.0.0",

  "description": "",

  "main": "index.js",

  "scripts": {

    "build": "ncc build index.js -o dist"

  },

  "keywords": [],

  "author": "",

  "license": "ISC",

  "dependencies": {

    "fastify": "^4.23.2",

    "hashids": "^2.3.0"

  },

  "devDependencies": {

    "@vercel/ncc": "^0.38.0"

  }

}

• index.js

const hashids = require('hashids')

 

const myid = new hashids('this is my salt', 10, 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890')

 

const Fastify = require('fastify')

 

const fastify = Fastify()

 

fastify.get('/', async (request, reply) => {

    console.log(myid.encode(1, 2, 3))

    reply.send({ hello: myid.encode(1, 2, 3) })

})

 

fastify.listen({

    port: 3000,

    host: "0.0.0.0",

    backlog: 511

}, (err, address) => {

    if (err) {

        console.error(err)

        process.exit(1)

    }

    console.log(`Server listening at ${address}`)

})

• 构建

yarn build

• docker-compose 文件

version: '3'

services:

   app:

     image: dalongrong/graaljs:23.1.0

     command: node --jvm --polyglot  /app/index.js

     ports:

       - "3000:3000"

     volumes:

     - ./dist:/app/

• 效果

 

说明

docker 镜像我已经push dockerhub了 dalongrong/graaljs:23.1.0 目前来说独立的graaljs 的确会简化node 与jvm 项目的集成，当然从实际测试来说graaljs 暂时还是不如nodejs 项目启动快速,但是对于业务有node 与java 互调用的场景是一个特别好的选择，比基于node-addon 的模式很很多
