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 🙏

接入指南

Vue 2 接入用例

import { createOcrUploader } from '@baturu/parts-ocr-sdk';

// 在 Vue 组件中调用 createOcrUploader 函数创建上传器实例
export default {
  data() {
    return {
      instance: null, // 上传实例
    };
  },
  mounted() {
    this.instance = createOcrUploader(this.$refs.uploader, {
      limit: 6, // 设置最大上传图片数量为 6
      confirmText: '确认结果', // 设置确认按钮的文本
      ocrLoadingImageUrl: 'https://abc.com/loading.gif', // 设置 OCR 识别加载中图片
      onUpload: async (file, progress) => {
        // 处理图片上传逻辑,并更新进度
        const url = await uploadFile({ file }, {
          onUploadProgress: ({ loaded, total }) => {
            progress(loaded / total); // 更新上传进度
          },
        });
        return url; // 返回 url
      },
      onPreview: (imgSrc, index, images) => {
        // 预览图片,这里的 previewImage 函数需自行实现
        previewImage(imgSrc, index, images);
      },
      onOcr: async imgSrc => {
        // 处理 OCR 识别逻辑
        const { model } = await executeOcr({ url: imgSrc });
        return model; // 返回 OCR 识别结果的相关信息
      },
      onConfirm: parts => {
        // 处理确认上传或识别结果的逻辑
        this.$emit('confirm', parts);
      },
      onError: err => {
        // 处理错误逻辑
        this.$message.warning(err.message); // 显示错误消息
      },
    });
  },
  beforeDestroy() {
    // 组件销毁前应同时销毁ocr实例,避免内存泄漏
    this.instance?.destroy();
  },
};
