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 🙏

run_func_serve

用于在服务端运行前端传来的函数, 可用于操作MongoDB数据库以及处理文件上传等

init

var rfs = require('run_func_serve')

// 初始化
// 设置默认的数据库名, 默认为 base
// 以及一个可以通过名称得到对应数据库的 async 方法
rfs.init({
	db_name: 'base',
	getDB: null
})

// 通过接口调用
route.post('/func', async (req, res) => {
	await rfs.run_func(req, res)
})

在前端使用

前端引入 run_func_client.js

import rfc from "run_func_serve/run_func_client";


// 初始化, 默认值: 'http://localhost:3002'
func.init({server: '', db_name: 'base'})

// 远程运行, 处理数据库(MongoDB)
func.run(async db => {
    return await db.collection('users')
        .find({}, {projection: {_id: 0})
        .toArray()
}).then(find_res = {
    console.log('rfc find result:', find_res)
})

// 其它形式, 支持队列及参数数组
func.run('queue', async db => {})
func.run([param1, param2, ...], async db => {})
func.run('queue', [param1, param2, ...], async db => {})

// 文件上传, 支持多文件上传, files: fileList.files
func.upload(files).then()

注意: ~~如果前端进行代码压缩, 需要保留 db 字段~~

1.0.6版本之后, 不再需要设置 mangle.reserved

terser({
	compress: {
		// drop_console: true
	},
	mangle: {
		reserved: [
			'db' 		// db, prom for run_func_serve
		]
	}
}
