# Hero Template Example
This folder contains the iris version of the original hero's example: https://github.com/shiyanhui/hero/tree/master/examples/app.
Iris is 100% compatible with `net/http` so you don't have to change anything else
except the handler input from the original example.
The only inline handler's changes were:
From:
```go
if _, err := w.Write(buffer.Bytes()); err != nil {
// and
template.UserListToWriter(userList, w)
```
To:
```go
if _, err := ctx.Write(buffer.Bytes()); err != nil {
// and
template.UserListToWriter(userList, ctx)
```
So easy.
