How to make axios call within callback of setState callback
0
I have two async call as follows. I try to wrap the axios call within the callback of this.setState, but It throws syntax error like , expected
this.setState(prevState => ({
condition: [...prevState.condition, { name: "readByGroup", operator: "IN ", value: groups }]
}))
}
this.props.getMetricsByContent(this.state.condition).then((data) => {
this.setState({isLoader: false});
if(data && Array.isArray(data) && data.length > 0){
let csvContent = papa.unparse(data);
this.download(csvContent, 'metrics.csv', 'text/csv;encoding:utf-8');
this.setState({statusMsg: "File Downloaded successfully"})
} else this.setState({statusMsg: "No records to download"})
})
What I tried is given below:
this.setState(prevState => ({
condition: [...prevState.condition, { name: "readByGroup", operator: "IN ", value: groups }]
this.props.getMetricsByContent(this.state.condition).then((data) => {
this.setState({isLoader: false});
if(data && Array.isArray(data) && data.length > 0){
let csvContent = papa.unparse(data);
this.download(csvContent, 'metrics.csv', 'text/csv;encoding:utf-8');
this.setState({statusMsg: "File Downloaded successfully"})
} else this.setState({statusMsg: "No records to download"})
})
}))

I don't see where you're running a callback function in the this.setState.
Try:
this.setState(prevState => ({
condition: [...prevState.condition, { name: "readByGroup", operator: "IN ", value: groups }]
}), () => {
this.props.getMetricsByContent(this.state.condition).then((data) => {
this.setState({isLoader: false});
if(data && Array.isArray(data) && data.length > 0){
let csvContent = papa.unparse(data);
this.download(csvContent, 'metrics.csv', 'text/csv;encoding:utf-8');
this.setState({statusMsg: "File Downloaded successfully"})
} else this.setState({statusMsg: "No records to download"})
}))
}
The key being the arrow function as the next paramater to setState.
