Services and Models
Services
General rules
- Services are mostly asynchronous, if vendor API is synchronous, convert it to asynchronous with promises
- A synchronous method must be sufixed with the keyword
Sync, eg: findSync() - Never import the implementation directly (example below)
Examples:
Implementation import
Never import the implementation directly:
WRONG:
import $MockChannelService from "@MockChannelService"; // WRONG
import $AppScreen from @AppScreen;
export default $AppScreen.declare("HomeScreen", {
...GOOD:
import $ChannelService from "@ChannelService"; // GOOD
import $AppScreen from @AppScreen;
export default $AppScreen.declare("HomeScreen", {
...Models
General rules
- Don’t access native data property (example below)
- Don’t update one property from native data (example below)
Examples:
Native data
Don’t access native data property:
WRONG:
let movie = new $Movie();
let movieName = movie.data.title; // WRONG
GOOD:
let movie = new $Movie();
let movieName = movie.name; // GOOD
Change native data
Don’t update one property from native data:
WRONG:
let movie = new $Movie();
movie.data.title = "New Title"; // WRONG Won't change movie.name as data is a POJO not watchable
GOOD:
let movie = new $Movie();
movie.data = { title: "New Title" }; // GOOD movie.name will change as data changed
