Load More – Pagination trick with react native

By Mr. Rahul March 15, 2022 React Native 0 Comments

Pagination is needed when records in hundreds, thousands and in millions. So today we try to find the solution for how to create pagination with load-more buttons in react native. In mobile apps generally we use a load more button so let’s start. For frontend we will use react native and backend you can choose according to your requirements like node js, PHP etc.

Highlights
1. Create load more button in component
2. create function for append load more records

1. Create load more button in component

{data && data.length<total?(
 <TouchableHighlight style={styles.btnGradientDiv} 
  underlayColor="#ffffff" 
  onPress = {() => {loadmore()}}>
 <LinearGradient
      start={{x: 0, y: 0}} end={{x: 1, y: 0}}
      colors={['#9b0000', '#720101']}
      style={[styles.btnDefault, styles.btnFull]}>
      <Text style={styles.TextStyle}>Load More</Text>
      </LinearGradient>
  </TouchableHighlight>):(<></>)}

{data && data.length<total?(

<TouchableHighlight style={styles.btnGradientDiv}

underlayColor="#ffffff"

onPress = {() => {loadmore()}}>

<LinearGradient

start={{x: 0, y: 0}} end={{x: 1, y: 0}}

colors={['#9b0000', '#720101']}

style={[styles.btnDefault, styles.btnFull]}>

</LinearGradient>

</TouchableHighlight>):(<></>)}

2. Create function for append load more records

 // Get Items.
const loadmore = async (id) => { 

    let sdata = {
          method: 'POST',
          //credentials: 'same-origin',
          //mode: 'same-origin',
          body: JSON.stringify({
              "id":id,
              "page": count                  
          }),
          headers: {
            'Accept':       'application/json',
            'Content-Type': 'application/json',
            //'X-CSRFToken':  cookie.load('csrftoken')
          }
    }
    await fetch(BASE_URL+'/fetch_transactions',sdata)
    .then((response) => response.json())
    .then(async (json) => {
      if(json.status && json.data && json.data.length>0) {

        let new_Data = data.concat(json.data)

        setData(new_Data)
        setCount(prevCount => prevCount + 1)  
        
      } else if(!json.status) alert(json.msg)


    }) 

}

// Get Items.

const loadmore = async (id) => {

let sdata = {

method: 'POST',

//credentials: 'same-origin',

//mode: 'same-origin',

body: JSON.stringify({

"id":id,

"page": count

}),

headers: {

'Accept': 'application/json',

'Content-Type': 'application/json',

//'X-CSRFToken': cookie.load('csrftoken')

}

await fetch(BASE_URL+'/fetch_transactions',sdata)

.then((response) => response.json())

.then(async (json) => {

if(json.status && json.data && json.data.length>0) {

let new_Data = data.concat(json.data)

setData(new_Data)

setCount(prevCount => prevCount + 1)

} else if(!json.status) alert(json.msg)

})

}
