decoders

• Fix: revert accidentally emitting $ReadOnlyArray types in array decoders

• Drop support for Node 7
• Declare inputted arrays will not be modified (treated as read-only)

• Fix type issues caused by too strict use of mixeds

• Make decoders fully Flow Strict compatible

• Make decoders fully Flow Strict compatible

• Upgraded debrief dependency
• Behave better in projects that have Flow's experimental.const_params
  setting turned on

• New decoders!
  • exact() is like object(), but will fail if the inputted object contains
    superfluous keys (keys that aren't in the object definition).

• Collect and report all nested errors in an object() at once (rather than error on the first error).

Breaking:

• Remove deprecated message argument to object()

• New decoders!
  • email validator based on the almost perfect email regex
  • url validator for validating HTTPS URLs (most common use case)
  • anyUrl validator for validating any URL scheme

• Much improved error messages! They were redesigned to look great in terminals and to summarize only the relevant bits of the error message, striking a balance between all the details and the high level summary.

• New feature: regex(), for building custom string decoders
• Tiny tweaks to improve error messages (more structural improvements are on the roadmap)

This is the first stable release, and marks a point where I'm comfortable with the public API and I expect no signature changes in it.

• BREAKING Removes the old public ("compat") API
• Finalize/settle on new public API

• Breaking change New API: simplified names, split up decoders from guards.
  What used to be called "decoders" in 0.0.x ("things that either return
  a value or throw a runtime error") are now called "guards" in 0.1.0.
  The meaning of the term "decoders" is now changed to a thing that either is
  an "Ok" value or an "Err" value.

  To convert to the new API, do this:

  // Old way
  import { decodeNumber, decodeObject, decodeString } from 'decoders';
  
  const decoder = decodeObject({
      name: decodeString(),
      age: decodeNumber(),
  });
  
  // -------------------------------------------------------------------
  
  // New way
  import { guard, number, object, string } from 'decoders';
  
  const guard = guard(object({
      name: string,
      age: number,
  }));
  

• Decoders have been split up into multiple files
• Tests were added
• Coverage has increased a bit
