Hi! I'm @azu.

I've worked on Open Source since 2010.
I've created 500+ npm pacakges and These are 10 million downloads a year.

I've created and now maintain several open-source libraries:

  • textlint is a linter for natural languages (2,000+, 30,000+ month downloads)
  • Secretlint improves security ecosystem of project
  • HonKit build books using Markdown (1,000+ )
  • Almin (400+)
  • rc-config-loader (200,000+ month downloads)
  • etc...

Also, I the main writer of some blogs about JavaScript and ECMAScript.

I've written JavaScript books as Open Source.
