axios – ReactJS state updates one step behind

I am trying to create a simple table using ReactJS to display user information. Here’s how the general code structure looks like:

class ParentComponent extends React.Component {
  state = { 
    data : () 
  }

  componentDidMount() {
    // initializes state with data from db
    axios.get("link/").then(res => {this.setState(data: res.data)});

    // I should be able to call this.getData() instead of rewriting the axios.get() function
    // but if I do so, my data will not show up

  }
  
  // retrieves array of data from db
  getData = () => {
    axios.get("link/").then(res => {this.setState(data: res.data)});
  }  

  render() {
    return (
      <div>
        <ChildComponent data={this.state.data} refetch={this.getData} />
      </div>
    )
  }
}

Each of the generated rows should have a delete function, where I’ll delete the entry from the database based on a given id. After the deletion, I want to retrieve the latest data from the parent component to be redisplayed again.

class ChildComponent extends React.Component {

  // deletes the specified entry from database
  deleteData = (id) => {
    axios.get("deleteLink/" + id).then(res => {
      console.log(res);
      // calls function from parent component to re-fetch the latest data from db
      this.props.refetch();

    }).catch(err => {console.log(err)});
  }

  render() {
    let rows = null;
    if(this.props.data.length) {
      // map the array into individual rows
      rows = this.props.data.map(x => {
        return (
          <tr>
            <td>{x.id}</td>
            <td>{x.name}</td>
            <td><button onClick={() => {this.deleteData(x.id)}}>Delete</button></td>
          </tr>
        )
      })

    }

    return (
      <div>
        <table>
          <thead></thead>
          <tbody>
            {rows}
          </tbody>
        </table>
      </div>
    )
  }
}

The two problems which I encountered here are:

1. Logically, I should be able to call this.getData() from within componentDidMount(), but if I do so, the table doesn’t load.
2. Whenever I try to delete a row, the table will not reflect the update even though the entry is removed from the database. The table will only be updated when I refresh the page or delete another row. Problem is, the component is always lagging behind by 1 update.

So far I have tried:

1. this.forceUpdate() – doesn’t work
2. this.setState({}) – empty setState doesn’t work either
3. changing componentDidMount to componentDidUpdate – error showing that I have “reached maximum depth” or something along that line
4. adding async await in front of axios – doesn’t work

Any help is appreciated. Thanks in advance.
