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 🙏

Downloads

Readme

将mongo的query语句转化成es的

单纯的分析mongo中查询关键词, 并转化

elastic version 1.7

目标

不是做一个完全的兼容转化, 选取mongo查询语法和es查询功能的一个共有子集, 对应起来

映射关系

  • $eq, $ne
  • $gt, $gte, $lt, $lte
  • $in, $nin
  • $regex
  • $exists
  • $size
  • $and
  • $or
  • $not
  • $and $or $not 嵌套

变相支持

  • $text:
{tags_string:{$text: '1boy'}}

{tags_string:{$text: '1boy head'}} // eq: tags_string like 1boy or head

{tags_string:{$text: '1boy AND head'}} // eq: tags_string like 1boy AND head
  • $script:
{any:{$script: "doc['num1'].value > 1"}} // 1: any 部分写什么都行, 仅是为了统一语法中的先写字段名的规则, 转化后会忽略,
{anx:{$script: "doc['num1'].value > 1"}} // 2: 与上行是等价的
{any:{$script: {script: "doc['num1'].value > p1", params: {p1: 2}}}} // 3: 可以设置参数

不支持

  • $nor
