v2.0.0

Hapi 17+ Support!

• Rewrote plugin using hapi-auth-cookie as base code (again)
• Decoupled plugin from Okanjo-App, no longer needed as a dependency
• Updated eslint/npm/travis configs
• SessionPlugin exports a register function, making it easy to register to an OkanjoServer instance.
• SessionCookiePlugin contains the full plugin implementation, usable with Hapi directly
• Updated tests, retrofitting and adding new tests for coverage
• Updated example app
• Updated docs
• Ditched yarn

Breaking Changes

• Plugin registration has changed. Use SessionPlugin.register(...) instead.
• Configuration has changed. It matches hapi-auth-cookie, except password has been removed, cache and report have been added.
• request.session interface has changed to use async functions (returns promises). They optionally take a callback for some backwards compatibility.
