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 🙏

安装 rust 环境

Readme

构建&编译

安装 rust 环境

根据您的操作系统,参照 https://www.rust-lang.org/tools/install 文档描述进行安装

安装成功后,除了rustc 编译器之外,同时会安装rust相关的工具链,其中cargo最为常用

安装完成后,打开新的终端 输入 cargo -v 查看是否已经成功安装 cargo 命令

安装wasm-pack

要构建我们的包,我们需要一个额外工具 wasm-pack。它会帮助我们把我们的代码编译成 WebAssembly 并制造出适用于web环境的wasm包。使用下面的命令可以下载并安装它:

cargo install wasm-pack

编译wasm

wasm-pack安装成功后,执行下面的命令以编译wasm包

SECRET=<your-secret> wasm-pack build --target=web --release

替换 为你的签名盐值

第一次构建和编译时间会比较长,需要下载依赖的rust库并编译,请耐心等待

如果速度仍然很慢,建议更换cargo国内源

更换 cargo 源

在你的cargo文件夹下新建 config 文件

macos中,文件夹地址在 ~/.cargo

cd ~/.cargo
touch config

然后编辑config文件,添加如下内容:

[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
replace-with = 'ustc'
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"

即可更换为ustc的源
