mobx-utils - npm Package Versions

3.1.1

• Introduced whenAsync, which is like normal when, except that this when will return a promise that resolves when the expression becomes truthy. See #66 and #68, by @daedalus28

3.0.0

Revamped fromPromise:

• It is now possible to directly pass a (resolve, reject) => {} function to fromPromise, instead of a promise object
• BREAKING fromPromise no longer creates a wrapping object, but rather extends the given promise, #45
• BREAKING Fixed #54, the resolved value of a promise is no longer deeply converted to an observable
• BREAKING Dropped fromPromise().reason
• BREAKING Improved typings of fromPromise. For example, the value property is now only available if .state === "resolved" (#41)
• BREAKING Dropped optional initialvalue param from fromPromise. use fromPromise.fulfilled(value) instead to create a promise in some ready state
• Introduced fromPromise.reject(reason) and fromPromise.resolve(value?) to create a promise based observable in a certain state, see #39
• Fixed #56, observable promises attributes state and value are now explicit observables

Introduced asyncAction

See the docs for details, but the gist of it:

import {asyncAction} from "mobx-utils"

mobx.configure({ enforceActions: "observed" }) // don't allow state modifications outside actions

class Store {
	@observable githubProjects = []
	@state = "pending" // "pending" / "done" / "error"

	@asyncAction
	*fetchProjects() { // <- note the star, this a generator function!
		this.githubProjects = []
		this.state = "pending"
		try {
			const projects = yield fetchGithubProjectsSomehow() // yield instead of await
			const filteredProjects = somePreprocessing(projects)
			// the asynchronous blocks will automatically be wrapped actions
			this.state = "done"
			this.githubProjects = filteredProjects
		} catch (error) {
			this.state = "error"
		}
	}
}
