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 🙏

tcbfs 是一个用于管理腾讯云 CloudBase 文件操作的模块,支持文件的上传、下载、删除、压缩和解压缩操作。

功能

  • 上传文件:支持上传单个文件和批量文件到云存储。
  • 下载文件:支持从云存储中下载单个文件和批量文件。
  • 删除文件:支持删除单个文件和批量文件。
  • 获取临时访问 URL:获取文件的临时访问 URL。
  • 组织文件路径:为压缩和解压缩操作做准备。
  • 压缩文件:支持压缩文件和目录。
  • 解压文件:支持解压缩文件。

安装

要安装 tcbfs,可以使用以下命令:

npm install tcbfs

使用

  • 为了实现方便直观的云存储操作,云存储的根目录当作 / 目录进行处理
  • 同时为了避免混淆,当前层级路径应使用 ./ 表示
  • 所有函数都是异步函数,应使用 async/await 调用

上传文件

上传单个文件到云存储:

const { upload } = require("tcbfs");

upload("cloud/path/to/file.txt", Buffer.from("File content"))
  .then((fileID) => console.log("File uploaded with ID:", fileID))
  .catch((err) => console.error("Error uploading file:", err));

上传多个文件到云存储:

const { multiupload } = require("tcbfs");

const files = [
  {
    cloudPath: "cloud/path/to/file1.txt",
    fileContent: Buffer.from("File 1 content"),
  },
  {
    cloudPath: "cloud/path/to/file2.txt",
    fileContent: Buffer.from("File 2 content"),
  },
];

multiupload(files)
  .then((fileIDs) => console.log("Files uploaded with IDs:", fileIDs))
  .catch((err) => console.error("Error uploading files:", err));

下载文件

下载单个文件:

const { download } = require("tcbfs");

download("cloud/path/to/file.txt")
  .then((fileContent) => console.log("File content:", fileContent))
  .catch((err) => console.error("Error downloading file:", err));

下载多个文件:

const { multidownload } = require("tcbfs");

const fileList = ["cloud/path/to/file1.txt", "cloud/path/to/file2.txt"];

multidownload(fileList)
  .then((fileContents) => console.log("File contents:", fileContents))
  .catch((err) => console.error("Error downloading files:", err));

删除文件

删除单个文件:

const { remove } = require("tcbfs");

remove("cloud/path/to/file.txt")
  .then((result) => console.log("File deleted:", result))
  .catch((err) => console.error("Error deleting file:", err));

删除多个文件:

const { multiremove } = require("tcbfs");

const fileList = ["cloud/path/to/file1.txt", "cloud/path/to/file2.txt"];

multiremove(fileList)
  .then((result) => console.log("Files deleted:", result))
  .catch((err) => console.error("Error deleting files:", err));

获取临时访问 URL

获取单个文件的临时访问 URL:

const { getTempFileURL } = require("tcbfs");

getTempFileURL("cloud/path/to/file.txt")
  .then((url) => console.log("Temporary file URL:", url))
  .catch((err) => console.error("Error getting temporary file URL:", err));

获取多个文件的临时访问 URLs:

const { getTempFileURLs } = require("tcbfs");

const fileList = ["cloud/path/to/file1.txt", "cloud/path/to/file2.txt"];

getTempFileURLs(fileList)
  .then((urls) => console.log("Temporary file URLs:", urls))
  .catch((err) => console.error("Error getting temporary file URLs:", err));

压缩文件

压缩文件或目录:

const { compressFiles } = require("tcbfs");

compressFiles({
  fileList: [
    { fileName: "file1.txt", fileContent: Buffer.from("Content of file 1") },
    { fileName: "file2.txt", fileContent: "local/path/to/file2.txt" },
  ],
  outputPath: "path/to/output.zip",
})
  .then(() => console.log("Files compressed successfully"))
  .catch((err) => console.error("Error compressing files:", err));

解压文件

解压文件:

const { decompressFile } = require("tcbfs");

decompressFile({
  inputPath: "path/to/compressed.zip",
  outputDir: "path/to/output/dir",
})
  .then(() => console.log("Files decompressed successfully"))
  .catch((err) => console.error("Error decompressing files:", err));
