@lore/models v1.0.0-beta.1
@lore/models
Purpose
Create a Model for every file in src/models and expose the resultant Models on lore.models.
Dependant Hooks
None.
Needed improvements
- PascalCase the models that get exposed on
lore.models(i.e.lore.models.Todoinstead oflore.models.todo)
Override Rules
Models typically need three things in order to be able to fetch a collection of resources
- The URL of the API server to hit
- The path to hit on the server (/todos for example)
- A method to parse the server response (such as to convert timestamps or moment.js objects or something)
For apps that only have a single API server, the endpoint the models should use is the same the app is
configured for by default. So that can be obtained from apiRoot in config/models.js. The path that
should be appended to the API Root can be derived from the model name (todo) and whether or not pluraize has
been set to true or false in config/models.js.
Then we just need to know how to parse the data, and for apps where the attribute field names in the models mirror
those in the API reponse (which is typical for new applications), even that method might be the same, especially if
you just want to convert globally applied timestamps like createdAt and updatedAt to an easier to work with format
like a moment.js object (unless you prefer to do the conversion in your components).
So for that scenario, the parse method can be pulled from config/models.js.
For apps that have been around for a while, and have survived API changes, it's not uncommon to have the parse methods
be a little more specific to that model, such as renaming fields befor the client code uses it to prevent API changes
from rippling through th applications. For those scenarios, you may find yourself starting to populate files
like src/models/todo.js.
And if you're application consumes data from more than one API server, you'll also need to update the urlRoot in
the individual src/models/todo.js files so they know which server they should talk to.
So given all of that, the models hook builds the configuration for each Model it creates using a set of
rules.
- It first pulls in
config/models.jsto get theapiRootandpluralizesetting. - It then overrides that config with anything it finds in the individual config file located at
src/models/todo.js, which will also include theparsemethod collections should use. - Finally, it fills in anything that still hasn't been defined using conventions (such as deriving the
urlRootfrom the model name and thepluralizesetting).
Example Usage
Given a project where a todo model has been created like so:
src
|-models
|-todo.jsThis hook will find it, create a Model from it (using a combination of the data in config/models.js and
src/models/todos.js, and expose the Model on lore.models.todo.
