Advantages of library independence
- Orion consumers who use the same libraries as us (such as dojo) wish to switch versions at their own pace.
- Size reduction and performance improvements as we eliminate library methods that are already available in the browser
- Simplification of styling so that we aren't combining a library theme with our own themes
- Simplification and consistency of coding practices so that we aren't wrestling different conventions/life cycles in the UI (dijit lifecycle vs. Orion, dijit layout vs. raw CSS, etc.).
Existing dependencies and proposed replacements
The remainder of this document categorizes our dependencies and gives status on the replacement candidates.
We have many dom utility methods sprinkled throughout the client code. Many of these are now available in our supported browser set. The following list shows method usage and replacement (this may expand to its own page).
- dojo.byId, dojo.query element.querySelector and element.querySelectorAll
- dojo.addClass, removeClass, toggle class element.classList.remove/add/toggle/contains
- dojo.hitch Function.bind
Deferred / Promise support
dijit UI components
- dijit BorderContainer, ContentPane, Splitter for page layout.
- BorderContainer, ContentPane and splitter were removed and replaced with CSS and an Orion-specific splitter.js
- dijit DropDownMenu, MenuItem
- dijit Tooltip
