5.2.0

  • createViewModel now has an additional field changedValues on the returned viewmodel, that returns a map with all the pending changes. See #172 by @ItamarShDev. Fixes #171 and #173
  • fromPromise().case: if the onFulfilled handler is omitted, case will now return the resolved value, rather than undefined. See #167 by @JefHellemans
  • createViewModel will now respect the enumerability of properties. See #169 by dr0p

5.1.0

  • fromPromise now accepts a second argument, a previous obsevable promise, that can be used to temporarily show old values until the new promise has resolved. See #160 by @ItamarShDev
  • createTransformer can now also memoize on function arguments, see #159 by @hc-12

5.0.4

  • Fixed #158, deepObserve not being published

5.0.3

  • Introduced deepObserve utility, through #154

5.0.2

  • Add sideEffects: false field in package.json to enable maximal tree shaking for webpack.
  • Fixed #134, prevent primitive key id collisions in createTransformer
  • Fixed typing issue where the .value field is not available without having a type assertion of the state first

5.0.0

  • Added MobX 5 compatibility. The package is also compatible with MobX 4.3.1+.
  • createViewModel now also copies computed properties to the view Model. Implements [#100].(mobxjs#100). Implemented through #126 by @RafalFilipek.

4.0.1

4.0.0

Updated mobx-utils to use MobX 4. No futher changes

3.2.2

  • toStream now accepts a second argument, fireImmediately=false, which, when true, immediately pushes the current value to the stream. Fixes #82

3.2.1

  • Fixed issue where whenAsync was not exposed correctly.
  • Added timeout parameter to whenAsync

3.2.0

  • Switched to rollup for bundling, bundle non-minified and include a es module based build. See #81 by @mijay

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"
		}
	}
}
