convert TextInput to uppercase with react-native

By -

I have an onChangeText that converts the text to uppercase when I'm writing, but the moment I start to delete some of the writing, the text begins to be duplicated.

<TextInput
placeholderTextColor="gray" value={name}
onChangeText={(text) => setName(text.toUpperCase())}
selectionColor="orange"
autoCapitalize='none'
autoCorrect={false}
selectTextOnFocus={false}
/>

Thanks for your help EDIT: I just checked the A DNS record for js.authorize.net and am getting the following result only: js.authorize.net. 100 IN CNAME js.authorize.net.cdn.cloudflare.net. Doing the same for js.authorize.net.cdn.cloudflare.net. does not return an A Record, unless I specifically instruct to use 1.1.1.1 as DNS server I...

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure.
