lore-hook-collections
Purpose
Iterates through all models in lore.models
and creates a corresponding Collections for each of them. This is done
so we can fetch collections of resources and not just individual resources.
Dependant Hooks
Depends on the models
hook being run first as it iterates through lore.models
.
Needed improvements
- Provide an option to not create collections for certain models.
- PascalCase the collections that get exposed on
lore.collections
(i.e.lore.collections.Todo
instead oflore.collections.todo
)
Override Rules
Collections 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, to extract the meaningful data from any paginated metadata wrapper that might exist
- Which Model it should create and pass the resultant data to, to make sure each resource also gets parsed correctly in turn
For apps that only have a single API server, the endpoint the collections should use is the same the app is
configured for by default. So that can usually be obtained from apiRoot
in config/models.js
. The path that
should be appended to the API Root can be derived from the models (todo
) and whether or not pluraize
has
been set to true or false in config/models.js
. The Model that knows how to parse the resultant resources is
typically going to be the model with the same name as the colletion (lore.models.todo
). The only piece that
can't be derived from other parts of the configuration is the parse method the Collection should use to extract
the collection of resources from the other metadata like pagination. So that method should be specified in
config/collection.js
. If the API follows consistent conventions across all collection endpoints (and there's
only a single API server) there isn't a common reason to ever need to define a src/collection/todo.js
file. If
you do, it's to override the previous semi-deriable configuration with something specific to that collection.
So given all of that, the collections
hook builds the configuration for each Collection it creates using a set of
rules.
- It first pulls in
config/models.js
to get theapiRoot
andpluralize
setting. - It then overrides that config with anything it finds in
config/collections.js
, which will also include theparse
method collections should use. - It then looks to see if collection file has been created in
src/collections
that matches the name of the model (todo
in this example). If one exists, it then overrides the previous config with anything it finds in that file. - Finally, it fills in anything that still hasn't been defined using conventions (such as deriving the
urlRoot
from the model name and thepluralize
setting).
Example Usage
Given a project where a todo
model has been created like so:
src
|-models
|-todo.js
This hook will find it, create a Collection with it, and expose the collection on lore.collections.todo
.
