Learn about vigilant mode.

This major release contains three important changes:

  • the codebase was migrated to TypeScript (7245b80)
  • rollup is now used instead of webpack to create the bundles (27de300)
  • code that provided support for ancient browsers (think IE8) was removed (c656192 and b2c7381)

There is now three distinct builds (in the build/ directory):

  • CommonJS
  • ESM with debug
  • ESM without debug (rationale here: 00d7e7d)

And three bundles (in the dist/ directory) :

  • engine.io.js: unminified UMD bundle
  • engine.io.min.js: minified UMD bundle
  • engine.io.esm.min.js: ESM bundle

Please note that the communication protocol was not updated, so a v5 client will be able to reach a v6 server (and vice-versa).
