Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

react-native-dropdown-autocomplete

npm npm

Based on https://bit.ly/2AFjUsj, the most significant advantage of this package among all others is that you can have multiple autocomplete's on your page after following instructions below. Works on Android and IOS.

Usage

Install the package
npm i react-native-dropdown-autocomplete
Wrap the page you want to have autocomplete on with withKeyboardAwareScrollView:
import React, {Component} from "react";
import {StyleSheet, View, SafeAreaView} from "react-native";
import {Ionicons} from "@expo/vector-icons";
import shortid from "shortid";
import {Autocomplete, withKeyboardAwareScrollView} from "react-native-dropdown-autocomplete";

class HomeScreen extends Component {
  handleSelectItem(item, index) {
    const {onDropdownClose} = this.props;
    onDropdownClose();
    console.log(item);
  }

  render() {
    const autocompletes = [...Array(10).keys()];

    const apiUrl = "https://5b927fd14c818e001456e967.mockapi.io/branches";

    const {scrollToInput, onDropdownClose, onDropdownShow} = this.props;

    return (
      <View style={styles.autocompletesContainer}>
        <SafeAreaView>
          {autocompletes.map(() => (
            <Autocomplete
              key={shortid.generate()}
              style={styles.input}
              scrollToInput={ev => scrollToInput(ev)}
              handleSelectItem={(item, id) => this.handleSelectItem(item, id)}
              onDropdownClose={() => onDropdownClose()}
              onDropdownShow={() => onDropdownShow()}
              renderIcon={() => (
                <Ionicons name="ios-add-circle-outline" size={20} color="#c7c6c1" style={styles.plus} />
              )}
              fetchDataUrl={apiUrl}
              minimumCharactersCount={2}
              highlightText
              valueExtractor={item => item.name}
              rightContent
              rightTextExtractor={item => item.properties}
            />
          ))}
        </SafeAreaView>
      </View>
    );
  }
}
const styles = StyleSheet.create({
  autocompletesContainer: {
    paddingTop: 0,
    zIndex: 1,
    width: "100%",
    paddingHorizontal: 8,
  },
  input: {maxHeight: 40},
  inputContainer: {
    display: "flex",
    flexShrink: 0,
    flexGrow: 0,
    flexDirection: "row",
    flexWrap: "wrap",
    alignItems: "center",
    borderBottomWidth: 1,
    borderColor: "#c7c6c1",
    paddingVertical: 13,
    paddingLeft: 12,
    paddingRight: "5%",
    width: "100%",
    justifyContent: "flex-start",
  },
  container: {
    flex: 1,
    backgroundColor: "#ffffff",
  },
  plus: {
    position: "absolute",
    left: 15,
    top: 10,
  },
});

export default withKeyboardAwareScrollView(HomeScreen);

Usage without data-driven content

You can also pass fixed array of items to the Autocomplete

const data = [
  "Apples",
  "Broccoli",
  "Chicken",
  "Duck",
  "Eggs",
  "Fish",
  "Granola",
  "Hash Browns",
];

Change valueExtractor and pass the data to Autocomplete without fetchDataUrl

<Autocomplete data={data} valueExtractor={item => item} />

While developing our react-native application I found out that there's no autocomplete library available which can satisfy a need for > 1 autocomplete on a page. Styles were overlapping and due to position: "absolute" we weren't able to actually trigger TouchableOpacity on an element from the list on android device. We used a library which provides dropdown with auto-adjusting position using measureInWindow on a ref, we tweaked it a bit and with autocomplete input and time-slicing implementation we managed to get what we need. Still we can't interact with TextInput component while dropdown is opened but this is the best result we got using React Native Modal.
