Boltzmann v0.5.0

Boltzmann is now implemented in 100% TypeScript. It can scaffold either JavaScript or TypeScript projects.

$ npm init boltzmann --typescript # for typescript
$ npm init boltzmann # for javascript

If you had previously used Boltzmann for TypeScript you will find that the type definitions are much more complete & fully featured.

Breaking changes

• TypeScript users must use import { .. } from './boltzmann' instead of import { .. } from './boltzmann.js' – note the lack of the .js.
• The signatures of handlers changed. Handlers are no longer called with route parameters as a second argument. Parameters are now available as context.params.
• Routing happens before middleware; middleware that adjusts the URL will no longer affect routing behavior
• AJV validates schemas for validate.{body,params,query}; invalid schemas will throw errors in development.
• AJV version bumped from v6 to v8.
  • dataPath is now instancePath. Dotted lookup inside is now /-based
    instead. E.g., given an error at "foo":
    • BEFORE: {"dataPath": ".foo.bar"}
    • AFTER: {"instancePath": "/foo/bar"}
  • Error messaging changed ("must" replaces "should"):
    • BEFORE: "should have required property 'bar'"
    • AFTER: "must have required property 'bar'"
  • All schema errors are now returned, not just the first.
  • ajv@7 changes how ajv instances are constructed and removes builtin
    formats and keywords. See 1.
  • ajv@8 changes some details about error formatting. See 2.
• Handy-redis upgraded from 1.8.1 to v2.2.1
  • This changes the exported type.
