Programming patterns

The following programming patterns are discussed in this chapter:

  • Loading resources asynchronously — Use the Loadable API to load metadata asynchronously for maps, layers, and other resources to do such things as monitor the load status of the resource, handle concurrent and repeated requests to load the resource, cancel a load, retry to load if previous attempts failed, and handle circumstances such as network outages or service interruption.

For a description of offline patterns, see Offline maps, scenes, and data in the Offline maps, scenes, and data chapter. Which offline pattern you choose determines whether or not your users can define their own map area, and, if they are editing, how multiple editors will sync their edits back to a web map or back to a branch version.
