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 🙏

消息主题

创建主题

需要通过dashboard或者命令行先创建 topic 否则会抛出异常: No topic route info in name server for the topic: xxx

可使用如下命令创建主题

  mqadmin updateTopic -b 172.25.96.1:10911 -t routingKey

消息类型

如果publish的消息类型跟当前topic的类型不一致 则会出现如下异常:

`Current message type not match with topic accept message types`

消息类型共支持四种: NORMAL TRANSACTION DELAYFIFO

创建主题的时候如果未指定消息类型则默认为 NORMAL

a. 如果需要消息支持事务 需要修改为 TRANSACTION 
b. 如果需要消息支持延时消息 需要修改为 DELAY 
c. 如果需要消息支持顺序消息 需要修改为 FIFO

可以在创建主题的时候指定消息的类型:

  mqadmin updateTopic -b 172.25.96.1:10911 -t routingKey -a +message.type=DELAY
  
  mqadmin updateTopic -c DefaultCluster -t DelayTopic -n 127.0.0.1:9876 -a +message.type=DELAY
  
  mqadmin updateTopic -c DefaultCluster -t FIFOTopic -o true -n 127.0.0.1:9876 -a +message.type=FIFO
  
  mqadmin updatetopic -n localhost:9876 -t TestTopic -c DefaultCluster -a +message.type=TRANSACTION
