Included add-ons

Koala manifesto

  • Koala is not a framework

    It empowers developers to quickly develop SEEK web services using Koa using whatever structure they see fit.

  • Koala does not wrap other packages

    The objects and types of JavaScript packages such as Axios and hot-shots should be used directly. While Koala may provide constructors for objects from those packages, developers should always be able to "bring their own instance".

  • Koala does not contain policy

    It does not enforce timeouts, set caching headers, expect certain error objects, etc. Whenever a default policy is unavoidable it should be called out in the documentation and made configurable.

  • Koala modules should be usable in isolation

    An application should not have to "buy in" to all of Koala at once. Modules should not require special middleware to set up their state.

  • Koala is not innovative

    It implements best practices from SEEK and follows internal SEEK RFCs and s2sauth where applicable. The modular, policy-free nature of Koala allows individual apps to opt-out of Koala's implementation for experimentation.

  • Koala is not a dumping ground

    It strictly contains functionality related to developing Koa web services at SEEK. It should not include features only relevant to a single application or team.
