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 🙏

pdf-to-img_fork

此项目fork自https://github.com/k-yle/pdf-to-img,

原项目将每个pdf页面直接暴露为Buffer类型,使用的时候通过fs.write直接存图片即可。

最近有需求,由于需要根据PDF内容提取部分页面并转为图片,所以需要一个在PDF中搜索的功能,由于原项目并未暴露PDFDocumentProxy,所以做了以下修改:

  1. 暴露了PDFDocumentProxy,方便外面根据需要使用。
  2. 提供search方法,用于搜索整个PDF文档。
  3. 提供searchInPage方法,用于在PDF文档的某页面搜索。
  4. 增加配置项searchViewLength,用于设置搜索返回的字符长度,即被搜索字符串前后的字符数。
