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 🙏

Readme

fastify-pithy-session

Fastify插件用于读取和设置 session

原理

  1. fastifyonRequest 钩子里面解析 session 同时计算 session 值的 hash 保存到 fastify.prevSessionHash 里面;如果有 renew = true,则在 fastify.prevSessionExpire 保存过期信息。
  2. fastifyonSend 钩子里面判断是否需要重新保存,依据如下:
    • 进行过 session 更改, 判断当前 sessionhash 是否和 fastify.prevSessionHash 一致。
    • rolling 是否为 true
    • renew = true 并且快要过期。

依赖

当前插件依赖 fastify-cookie

安装

npm i fastify-cookie fastify-pithy-session

配置

引入并注册到 fastify 插件。

const fastify = require('fastify')();
app.register(require('fastify-cookie'), {
  // 如果 session 配置了 signed 则需要添加这个参数进行签名。
  secret: ['23a79fa38d2578d6'],
});
fastify.register(require('@tenny/fastify-session'), {
  renew: true,
  rolling: false,
  key: 'fastify_sess',
  cookie: {
    maxAge: 86400, // 到期时间, 一天
    httpOnly: true,
    signed: true,
  },
});

fastify.listen(3000);

配置项

  1. key - { String }: cookie key,默认为:'fastify_sess'
  2. rolling - { Boolean }: 强制每一次响应的时候都进行一次数据保存,默认为:false
  3. renew - { Boolean }: 当 session 快过期的时候,保存数据,重新刷新有效期,默认为:false
  4. cookie - { Object }:fastify-cookie Sending options配置项,默认:{ maxAge: 86400, httpOnly: true, signed: true }

如果同时配置了 rollingrenewrolling 的优先级高于 renew,就是说如果配置了 rolling 则不需要配置 renew

使用

// 1. 获取 session
let session = req.session;

// 2. 设置 session
req.session = { login: true };
// 或者
req.session.login = true;
