Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

lemon-hello-api

Basic Serverless Hello API with Lambda + API Gateway + Web Socket + SNS + SQS + KMS

  • Hello Nodejs DevOps Project with babel + eslint + jest + supertest + codecov + travis

  • Integrate with Slack + CloudWatch Alarm

설명 (Description)

  • Nodejs 기반 오픈소스 표준 개발 환경 구성안.
  • AWS CloudWatch 의 내용을 lemon-hello-sns으로 수신 함 -> 이후 슬랙으로 전달
  • 슬랙 webhook를 이용하여, 해당 슬랙 채널에 메세지를 보냄

사용법 (Usage)

  • Nodejs 에서 모듈로 이용 (intall package with npm)

    # npm 으로 패키지 설치.
    $ npm install lemon-hello-api --save
  • Case 1 에러 발생시 SNS로 정보 보내기. (Report error information via SNS)

    const payload = {...};
    try {
        ...
    } catch (e){
        const hello = require('lemon-hello-api');
        // `LS=1` means 'log silence'
        const sns = hello.lemon({ LS: '1' })('sns');
        const msgId = await $sns.reportError(e, payload);
    }
  • 슬랙으로 에러 정보 표시. ()

    SlackError

설치하기 (Installation)

[전체 순서]

  1. env/lemon.ymlenv/config.js 파일 복제하여 별도 구성 (customize config files)
  2. 환경 변수의 SLACK_PUBLIC 값을 변경. (change SLACK_PUBLIC address by slack webhook)
  3. KMS 로 슬랙 채널 WebHook 암호화 시키기. (encrypt slack webhook url with KMS, and update SLACK_PUBLIC)
  4. npm run deploy 으로 AWS 클라우드에 올리기 (deploy to AWS cloud npm run deploy)
  5. 그리곤, 즐기자~~ (enjoy~)

STEP.1 KMS로 설정 내용 암호화 하기

  • KMS 마스터 키ID 생성하기 (최초 생성) (Create master kms-id for 1st time)

    # 최초의 사용자 키 생성히기.. (create initial master-key in KMS)
    $ aws kms create-key --profile <profile> --description 'hello master key'
    {
        "KeyMetadata": {
            "KeyId": "0039d20d-.....-387b887b4783",
        }
    }
    # Alias 생성하기 ('0039d20d-.....-387b887b4783'은 앞에서 생성된 KeyId 항목으로 변경) (create alias)
    $ aws kms create-alias --profile <profile> --alias-name alias/lemon-hello-api --target-key-id 0039d20d-.....-387b887b4783
  • (참고) 암호화 테스트 하기. (Test encrypt)

    # 'hello lemon' 를 <kms-key-id>로 암호화하기...
    $ aws kms encrypt --profile <profile> --key-id alias/lemon-hello-api --plaintext "hello lemon" --query CiphertextBlob --output text

STEP.2 AWS 클라우드에 배포 (Deploy to AWS Cloud)

  • AWS Lambda 에 배포

    # npm 명령어 실행. (profile <lemon>)
    $ npm run deploy.lemon

개발 (Development)

  • 로컬에서 API 서버로 실행 (runs for local development)

    # express API 서버 올리기 (profile <lemon>)
    $ npm run express.lemon
    
    # httpie 로 요청하기 
    $ http ':8888/hello/'
    
    # KMS 작동 여부 확인하기. (test encrypt via api)
    $ http ':8888/hello/0/test-encrypt'    

Travis 연동

# install travis-cli (MacOS)
$ brew install travis

# encrypt npm token
$ travis encrypt <NPM Token> --add deploy.api_key
