React-Redux - Create a Search Filter [closed]

Answer 1

It looks like your code is missing some key elements for Redux to work. You need to dispatch a Redux action when your search input changes that will in turn update the store. Right now you're merely setting the local state of SearchBar when the input changes. Secondly, your reducer doesn't modify the state, it's always returning the same array.

Something along these lines.

Your actions file might look like this:

export const SEARCH = 'SEARCH';

export function search(value) {
  return {type: SEARCH, value};
}

Then your reducer might look like this:

import {SEARCH} from './actions';

const initialState = {contents: ['Mirististica', 'Vet'], value: '', works: []};

export default function reducer(state = initialState, action) {
  switch(action.type) {
    case SEARCH: {
      const {value} = action;
      const works = state.contents.filter((val) => val.includes(value));
      return {...state, value, works};
    }
    default:
      return state;
  }
}

Then in your SearchBar:

import React, {Component} from 'react';
import {connect} from 'react-redux';
import {bindActionCreators} from 'redux';
import {search} from './actions';

class SearchBar extends Component {
  render() {
    const {search, value} = this.props;

    return (
         search(e.target.value)}
          value={value} />
    );
  }
} 

function mapStateToProps({works}) {
  return {value: works.value};
}

function mapDispatchToProps(dispatch) {
  return bindActionCreators({search}, dispatch);
}

export default connect(mapStateToProps, mapDispatchToProps)(SearchBar);

Your WorkList component merely needs to listen for changes to works in the Redux store.

import React, { Component } from 'react';
import { connect } from 'react-redux';

class WorkList extends Component {
  render() {
    const {works} = this.props;

    return (
      {works.map((work) => )}

        

          

            
Nome
          
        
        
{work}
      
    );
  }
}

function mapStateToProps({works}) {
  return {
    works: works.works
  }
}

export default connect(mapStateToProps)(WorkList);
