Create Lightning Component

Step 1:- Create Lightning Component : googleNewsCmp.cmp

From Developer Console >> File >> New >> Lightning Component

googleNewsCmp.cmp [Lightning Component File]

    <aura:component controller="googleNewsController2" implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" description="c:googleNewsCmp">

    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>

    <aura:attribute name="itemList" type="List"/>

    <aura:attribute name="titleList" type="List"/>

    <aura:attribute name="linkList" type="List"/>

    <aura:attribute name="descList" type="List"/>

    <aura:attribute name="jsnonStr" type="Object"/>

    <aura:attribute name="accName" type="String"/>

     <aura:handler name="change" value="{!v.accName}" action="{!c.doInit}"/>

```
    <lightning:card>
```

        <div class="slds slds-p-around_medium">

```
 
```

            <h3 style="background:#eee; border:1px #ccc solid; padding:5px;"><strong style="color:#ab0000; font-size:16px;">News :- </strong> <span style="color:#0099cf; font-size:16px;"> {!v.accName}</span></h3>

```
            <br/>
```
```

                <aura:iteration items="{!v.itemList}" var="row">

```
                    <tr>
```
```
                        <td >

```
```
        </div>
```
```
    </lightning:card>  
```
```
</aura:component>
```

Create JavaScript Controller

Step 2:- Create Lightning Component : googleNewsCmpController.js

From Developer Console >> File >> New >> Lightning Component >> JavaScript Controller

googleNewsCmpController.js [JavaScript Controller]

```
   ({
```

	doInit:function(component,event,helper){

```
      helper.getGoogleNews(component);
```

      helper.accNewsHelper(component);

```
    },
```
```
})
```

Create JavaScript Helper

Step 3:- Create Lightning Component : googleNewsCmpHelper.js

From Developer Console >> File >> New >> Lightning Component >> JavaScript Helper

googleNewsCmpHelper.js [JavaScript Helper File]

```
   ({
```

    getGoogleNews:function(component,event,helper){

        action.setCallback(this, function(response){

            var state = response.getState();

            //alert('state_1 ' + state );

```
            if(state == "SUCCESS"){

                var results = response.getReturnValue();

                 //console.log('AAAA' + JSON.stringify(results));

```

                for (var i = 0; i < myObj.channel.item.length; i++) {

```
 
```

                    component.set("v.titleList", myObj.channel.item[i].title);

                    component.set("v.linkList", myObj.channel.item[i].link);

```
