I did:

• Search for if my issue has already been submitted
• Make sure I'm reporting something precise that needs to be fixed
• Give my issue a descriptive and concise title
• Create a minimal working example on JsFiddle or Codepen
  (or gave a link to a demo on the Selectize docs)
• Indicate precise steps to reproduce in numbers and the result,
  like below

[replace me with a short description of issue]

Steps to reproduce:

1. npm install @selectize/selectize
2. ls node_modules/@selectize/selectize

Expected result:
LICENSE README.md dist index.d.ts package.json

Actual result:
LICENSE README.md dist package.json

index.d.ts is missing from the directory and is needed when using typescript
