Automatic configuration of Models in Application

[kjdelisle]

Story

As a LoopBack 4 developer, I'd like my models to automatically be loaded into my application on boot, so that I don't have to write tons of bind calls myself.

Acceptance Criteria

• On application boot
  • Read src/models by default (configurable)
  • Parse the JS (TS) files as models and bind them to the app-level context
  • Parse the JSON/YAML files as metadata and call the underlying model / property decorator functions to associate that metadata with the corresponding JS/TS model files
    Ex.

const modelClass = loadModel(modelPath);
const metadataObject = loadMetadata(metaPath);
// @model is just model
model(metadataObject)(modelClass);

• Docs on loopback.io
• Blog post about the new functionality
