# DEPRECATED



| Deprecated |

|-------|

| This Dialogflow client library and Dialogflow API V1 [have been deprecated and will be shut down on October 23th, 2019](https://blog.dialogflow.com/post/migrate-to-dialogflow-api-v2/). Please [migrate to Dialogflow API V2](https://cloud.google.com/dialogflow-enterprise/docs/migrating). |



You can use this library as common pre-built .js ([choose there](target)).



Or you can install it with nodejs and that import as es6 (or .ts) module. See below. 



`npm install [email protected]`



# Usage



## .textRequest



```javascript



const client = new ApiAi.ApiAiClient({accessToken: 'YOUR_ACCESS_TOKEN'});

const promise = client.textRequest(longTextRequest);



promise

    .then(handleResponse)

    .catch(handleError);



function handleResponse(serverResponse) {

        console.log(serverResponse);

}

function handleError(serverError) {

        console.log(serverError);

}



```



## .eventRequest



```javascript

const promise = client.eventRequest("EVENT_NAME", options);

```



# TypeScript and ES6



This SDK written with Typescript and all it's sources are available in this package. So basically if you are using something like *webpack* or *browserify* with ES6 imports and so on, you can just install this SDK with `$ npm install api-ai-javascript --save-dev` command and then import original sources with something like:



```javascript



import {ApiAiClient} from "api-ai-javascript";



const client = new ApiAiClient({accessToken: 'YOUR_ACCESS_TOKEN'})



.textRequest('Hello!')

    .then((response) => {/* do something */})

    .catch((error) => {/* do something here too */})



```



*Note:* If you are going to build es5 version of your bundle with ApiAiClient inside, please add some typings for promises (e.g. @types/es6-promise)



You also can import and use all defined interfaces and ApiAiConstants:



```javascript

import {IRequestOptions, IServerResponse, ApiAiConstants} from "api-ai-javascript/ApiAiClient"

const lang = ApiAiConstants.AVAILABLE_LANGUAGES.EN;

```



You can find full list of interfaces [here](ts/Interfaces.ts)



# Development



* Checkout from this repository, do not forget to switch to "v2" branch

* run `$ npm install`

* run `$ webpack -w` or just `$ npm start` (as an option for non globally installed dev-server - `$ ./node_modules/.bin/webpack-dev-server`)

* develop! (webpack will automatically compile SDK to ./target/ApiAi.js file on each change, just include it into some test HTML file (./demo/index.html will probably do the job) and test it).



# Building



`$ npm run-script build` command will build everything



# Testing



`$ npm test`

## 2.0.0-beta.18

* some minor typings changes

## 2.0.0-beta.17

## 2.0.0-beta.14

## 2.0.0-beta.13

* IStreamClient is aligned with StreamClient needs, thanks to @muuki88 (#26)

* Callbacks in IStremClientOptions are now typed properly

* Added IStreamClient.getGain(): GainNode (#25) to allow set up gain of listener

* Fixed UTF8 requests, thanks to @elaval (#24)

## 2.0.0-beta.12

* Possibility to import ApiAiClient separately from ApiAiStreamClient 

* Typescript project demo setup added 

## 2.0.0-beta.8

### Breaking changes:

* Main class renamed from Client to ApiAiClient

* StreamClient renamed (in exports at least) to ApiAiStreamClient

* StreamClient class is no longer available inside main ApiAiClient class and now should be passed directly in ApiAiClient constructor: `const client = new ApiAiClient("ACCESS_TOKEN", {streamClientClass: ApiAiStreamClient})`.That was made to allow building your applications without streamclient at all (streamclient now takes about 70% of whole library). And also there will be other implementation of streamClient in the future

### Non-breaking changes:

* Demo updated
