coalesceFindRequests{boolean}
By default the JSONAPIAdapter will send each find request coming from a store.find
or from accessing a relationship separately to the server. If your server supports passing ids as a query string, you can set coalesceFindRequests to true to coalesce all find requests within a single runloop.
For example, if you have an initial payload of:
{ post: { id: 1, comments: [1, 2] } }
By default calling post.get('comments')
will trigger the following requests(assuming the comments haven't been loaded before):
GET /comments/1 GET /comments/2
If you set coalesceFindRequests to true
it will instead trigger the following request:
GET /comments?filter[id]=1,2
Setting coalesceFindRequests to true
also works for store.find
requests and belongsTo
relationships accessed within the same runloop. If you set coalesceFindRequests: true
store.findRecord('comment', 1); store.findRecord('comment', 2);
will also send a request to: GET /comments?filter[id]=1,2
Note: Requests coalescing rely on URL building strategy. So if you override buildURL
in your app groupRecordsForFindMany
more likely should be overridden as well in order for coalescing to work.
