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 🙏

// 整个编辑器外框
.container {
	position: absolute;
	top: 0;
	bottom: 1px;
	width: 100%;
	background-size: cover;
	background-image: url(https://p3.ssl.qhimg.com/t0121c4f255f95c5e79.jpg);

	// 头部工具栏
	.headbar {
		background-color: rgba(0, 0, 0, 0.1);
		.left-btn-list, .right-btn-list {
			// 按钮分组分隔线
			.btn-group:after {
				border-right: 1px solid rgba(255, 255, 255, 0.4);
			}
			// 按钮
			a.md-btn {
				color: rgba(255, 255, 255, 0.8);
				&:hover, &.focus{
					background-color: rgba(255, 255, 255, 0.3);
					color: rgba(0, 0, 0, 0.4);
				}
			}
		}
	}

	// 主体部分
	.main-area {
		background-color: none;
		// 左半边编辑器部分
		.editor {
			background-color: rgba(255, 255, 255, 0.1);
			.CodeMirror {
				color: #fff;
			}
			
			// 左侧行数显示栏
			.CodeMirror-gutters {

				}
			}
			
			// 左侧行数
			.CodeMirror-linenumber{
				color: rgba(255, 255, 255, 0.6);
			}
			
			// 光标
			// 编辑器中闪烁的光标是用DOM模拟的,所以可以自定样式
			.CodeMirror-cursor{
				border-left-color: #fff;
			}
			
			// 选中范围
			.CodeMirror-focused .CodeMirror-selected { 
				background: rgba(0, 0, 0, 0.3); 
			}
		}
		
		// 预览部分
		.preview {
			background-color: none;
			color: #fff;
			// 自定义markdown样式
			.md-text{
				font-size: 16px;
				line-height: 28px;
			
				h1{}

				blockquote {
					p {}
				}
			
				p {}
			
				a, a:link, a:hover, a:visited {}
				
				a:hover {}
				
				hr {}
			
				img {}
			
				.image-caption {}
				
				pre {
					code {}
					
					code.hljs {}
				}
				
				ol, ul {}
			}
		}
	}

	// 底部部分
	.bottom-bar {
		background-color: rgba(0, 0, 0, 0.1);
		.wordnum {
			color: #fff;
		}
	}
}

// 自定义关灯效果
.container.dark {
	background-image: none;
	background-color: rgb(38, 38, 38);
	.main-area {
		color: rgb(180, 180, 180);
		.editor {
			.CodeMirror {
				color: rgb(210, 210, 210);
			}
		}
	}
}

事件监听

组件允许注册autoSave、saveText、textUpdate事件,你可以选择是否监听这些事件:

<markdown-editor
	@autoSave="autoSave"
	@saveText="saveText"
	@textUpdate="textUpdate">
</markdown-editor>

textUpdate(text)

编辑文档内容变化时触发,里面会传入一个text参数,表示当前的内容;

autoSave()

如果你有实时保存的需求,可以监听这个事件。这个事件在用户输入间隙触发,你可以在里面加入本地保存等逻辑。

这个事件不带任何参数,只作为一个信号传递。如果需要用到文章内容,需要从上一个事件textUpdate传递。

saveText

这个事件会在用户按下 Ctrl + S 时触发,你可以在其中实现上传保存等逻辑。

后续计划

有什么需求请尽管提。。。
