# For Developers
## ViewHelpers
We have added a few ViewHelpers with this extension to get date of last comment in a News and to get count of number of comments in each News.
For this, you have to add a Namespace of ViewHelper.
```language theme={"theme":{"light":"github-light","dark":"github-dark"}}
xmlns:nscomment="http://typo3.org/ns/Nitsan/NsNewsComments/ViewHelpers"
```
Check this for more details:
## Get Date of Last comment in a News
To get date of last comment in a news, add following code.
```language theme={"theme":{"light":"github-light","dark":"github-dark"}}
| Last Comment on {newsComment.crdate}
```
Check this for more details:
## Get count of number of comments in a News
To get date of last comment in a news, add following code in List.html
```language theme={"theme":{"light":"github-light","dark":"github-dark"}}
Comments: {nscomment:count(newsuid: newsItem.uid)}
```
Check this for more details:
Above ViewHelpers are supported in V8, V9 & V10 only.
## Routing in TYPO3 9 & 10
Since version 9.5, TYPO3 supports speaking URLs and if you have used the typeNum for any Ajax related work then you also need to add **routeEnhancers** like **routeEnhancers > PageTypeSuffix > map > nsnewscomment: 99** in your site configuration.
```YAML theme={"theme":{"light":"github-light","dark":"github-dark"}}
routeEnhancers:
PageTypeSuffix:
type: PageType
default: /
index: ''
map:
/: 0
nsnewscomment: 99
```
