TraitFetch

Registry / Methods / Usages

Registers fetch() requests that will be automatically stopped and removed at Remove Phase. This uses JFactoryFetch which inherits from JFactoryPromise, allowing Request Abortion and Promise Chain Expiration.

Registry

myComponent.$.requests

Injected Methods

$fetch(registryId {string}, url {string}, fetchOptions {object})

Returns: JFactoryFetch resolved with the Fetch Response.
See also $fetchText() and $fetchJSON()

Defers current Phase: This method registers a Task that blocks the resolution of the current Phase (if any) until the whole Task chain (including subpromises) is resolved.

Auto completed: The promise chain is completed and expired as soon as all subpromises are resolved. This behavior can be disabled by setting anyPromiseOfTheChain.$chain.chainConfig.chainAutoComplete = false before the promise chain is completed.

Auto removed: This Subscription is removed as soon as its Promise Chain is completed.

myComponent.$fetch("myFetch", "asset.html", {
    cache : 'no-cache'
})
    .then(fetchResponse => {})

$fetchText(registryId {string}, url {string}, fetchOptions {object})

Returns: String

Same as $fetch() but resolved as String.

$fetchJSON(registryId {string}, url {string}, fetchOptions {object})

Returns: Object

Same as $fetch() but resolved as JSON Object.

$fetchRemove(registryId {string}, reason {string} = "$fetchRemove()")

Expires and removes the fetch registered with the key registryId previously created by $fetch(). An optional reason can be given for debugging the aborted Promise Chain.

$fetchRemoveAll(removePhase)

(Automatically called at Remove Phase)

Expires and removes any JFactoryFetch previously created by $fetch() if their Remove Phase match the given removePhase.
