Usage
Initialization example:
import { OzoneClient } from 'ozone-typescript-client'
import UserCredentials = OzoneClient.UserCredentials
import OzoneCredentials = OzoneClient.OzoneCredentials
import ClientConfiguration = OzoneClient.ClientConfiguration
import newOzoneClient = OzoneClient.newOzoneClient
let client: OzoneClient.OzoneClient
async function init() {
const credentials = new UserCredentials('ozoneUser', 'ozonePassword')
const config: ClientConfiguration = {
ozoneURL: `http://my.ozone.domain/ozone`,
ozoneCredentials: credentials
}
client = newOzoneClient(config)
await client.start()
}
Using API client example:
import { OzoneClient } from 'ozone-typescript-client'
import { Video, toPatch } from 'ozone-type'
declare function getClient(): OzoneClient.OzoneClient
const videoClient = getClient().itemClient<Video>('video')
const myOriginalVideo = await videoClient.findOne('uuid-yyyy-zzz')
const videoToUpdate = toPatch(myOriginalVideo)
videoToUpdate.name = 'a new name'
const updatedVideo = await videoClient.save(videoToUpdate)
login application example
import { OzoneClient } from 'ozone-typescript-client'
import UserCredentials = OzoneClient.UserCredentials
import ClientStates = OzoneClient.states
import { getDefaultClient } from 'ozone-default-client'
import once from 'ozone-components-utils/once'
export class PageLoginDefault extends Polymer.Element {
/* ... */
ready(): void {
super.ready()
const defaultClient = getDefaultClient()
defaultClient.onEnterState(ClientStates.STOPPED,() => {
this.set('isConnected', false)
})
defaultClient.onEnterState(ClientStates.AUTHENTICATED,() => {
this.set('isConnected', true)
})
if (defaultClient.authInfo) {
this.set('isConnected', true) // client is already logged
}
}
public async submitForm(e: Event): Promise<void> {
/* ... */
const updateMessagesOnError = once(() => {
this.set('isConnected', false)
const err = defaultClient.lastFailedLogin
if (err && err.status === 400) {
this.set('errorMessage', this.localized.msgEmptyCredentials)
} else if (err && err.status === 403) {
this.set('errorMessage', this.localized.msgInvalidCredentials)
} else {
this.set('errorMessage', this.localized.msgUnknownError)
}
})
const defaultClient = getDefaultClient()
defaultClient.onEnterState(ClientStates.AUTHENTICATION_ERROR, updateMessagesOnError)
const userCredentials: UserCredentials = new UserCredentials(this.username, this.password)
defaultClient.updateCredentials(userCredentials)
try {
// start if needed
await defaultClient.start()
} catch (err) {
// error are handle inside the client state machine
}
}
}
