v50

• Improve build performance to burn the server CPU cores! Before this, to build a module which has heavy deps maybe very slow since the single build task only uses one CPU core.
• Rewrite the dts transformer to get better deno types compatibility and faster transpile speed, but still lot of types are not working in Deno. (this is why the ?no-check exists)
• Add Deno testing CI on Github.

v49

• Improve the build process to fix an edge case reported in #118

   const Parser = require('htmlparser').Parser;

  esm (v48) output:

   import htmlparser2 from '/v48/[email protected]/es2021/htmlparser2.js'
   const Parser = htmlparser2.Parser; // Parser is undefined

  the expected output was fixed in v49:

   import { Parser as htmlparser2Parser } from '/v48/[email protected]/es2021/htmlparser2.js'
   const Parser = htmlparser2Parser; // Parser is a class

• Add more polyfills for Deno, huge thanks to @talentlessguy (#117)
  • path
  • querystring
  • url
  • timers
• Better self-hosting options improved by @jimisaacs, super! (#116, #119, #120, #122)
• Add Unlimited(max to 1PB) Storage to store builds and cache via NFS on esm.sh back server behind Cloudflare

v48

• Improve cjs-lexer service to handle the edge case is shown below:

   function debounce() {};
   debounce.debounce = debounce;
   module.exports = debounce;

  esm output:

   export { debounce } // this was missed
   export default debounce

• Ignore ?target in Deno (fix #109)
• Add Storage Interface to store data to anywhere (currently only support postdb + local FS)

v47

• Improve dts transformer to use cdn domain (fix #104)
• Update polyfills (fix #105)

v46

• Split modules based on exports defines (ref #78)
• Add cache-folder config for yarn add
• Improve resolveVersion to support format 4.x (fix #93)
• Import initESM to support bare exports in package.json (fix #97)
• Bundle mode should respect the extra external (fix #98)
• Support node:path importing (fix #100)
• Pass ?alias and ?deps to deps (fix #101)
• Improve cjs-lexer sever (fix #103)
• Upgrade rex to 1.4.1
• Upgrade esbuild to 0.12.24

v45

• Improve build performance
• Filter cjs-moudle-lexer server invalid exports output
• Improve resolveVersion function to support format like 4.x (fix #93)
• Improve dts transform (fix #95)

v44

• Add Alias feature (#89)

  import useSWR from 'https://esm.sh/swr?alias=react:preact/compat&[email protected]'

  The origin idea was came from @lucacasonato.
