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 🙏

moleculer-context-logger

给 moleculer项目的ctx 添加 logger,满足项目的requestID需求

可以通过ctx.logger.info打印日志, 满足使用moleculer的微服务项目中请求ID的需求

nodejs版本 >= 8.0

如何使用

npm install moleculer-context-logger

在一般service的schema文件中

const { ContextLoggerServiceMixin } = require('moleculer-context-logger')

module.exports = {
  mixins: [ ContextLoggerServiceMixin ]
}

给ctx添加了ctx.logger对象,所以在action中可以直接类似this.logger

ctx.logger.info('some log')

在应用了moleculer官方提供的api网关mixin的service的schema文件中

const ApiGateway = require('moleculer-web')
const { ContextLoggerApiMixin } = require('moleculer-context-logger')
module.exports = {
  mixins: [ ApiGateway, ContextLoggerServiceMixin ]
}

在routes的aliases函数里面

'POST someurl' (req, res) {
  let ctx = req.$ctx
  ctx.logger.info('some log')
}
