How do I make a UI component library in JavaScript?

To create a UI component library in JavaScript, you need to follow these steps:

  1. Decide on a framework: You can choose to build your component library using a UI framework such as React, Vue, or Angular.
  2. Define your components: Decide on what components you want to include in your library. Think about the components that you use repeatedly in your projects and aim to make them reusable.
  3. Implement the components: Write the code for each component, making sure to follow the framework's guidelines and best practices.
  4. Test the components: Test each component thoroughly to ensure it works as expected and fix any bugs you find.
  5. Document the components: Write documentation for each component, including how to use it, props, and example code.
  6. Package the components: Package your components into a library using a tool such as webpack or Rollup.
  7. Publish the library: Publish the library to a package manager such as npm, so others can use it in their projects.

Write a button component by Vue.

<template>
  <button :class="className" @click="onClick">
    {{ label }}
  </button>
</template>

<script>
export default {
  props: {
    label: {
      type: String,
      required: true
    },
    className: {
      type: String,
      default: 'btn'
    }
  },
  methods: {
    onClick() {
      this.$emit('click');
    }
  }
};
</script>

This component takes two props: label and className. The label prop is a string that is displayed on the button, and the className prop is a string that is used as the class name for the button element.

The component emits a click event when the button is clicked, which can be listened for and handled by the parent component.

This is a basic example of a button component, and you can add more functionality or styles to suit your needs.

Write a table component by Vue.

<template>
  <table :class="className">
    <thead>
      <tr>
        <th v-for="header in headers" :key="header">
          {{ header }}
        </th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="row in rows" :key="row.id">
        <td v-for="value in row" :key="value">
          {{ value }}
        </td>
      </tr>
    </tbody>
  </table>
</template>

<script>
export default {
  props: {
    headers: {
      type: Array,
      required: true
    },
    rows: {
      type: Array,
      required: true
    },
    className: {
      type: String,
      default: 'table'
    }
  }
};
</script>

This component takes two required props: headers and rows. The headers prop is an array of strings that are used as the header labels, and the rows prop is an array of objects that represent the table rows.

The component also takes an optional className prop that is used as the class name for the table element.

This is a basic example of a table component, and you can add more functionality, such as sorting or pagination, to suit your needs.

Write a table component with sorting and fixed header by Vue.

<template>
  <table :class="className">
    <thead>
      <tr>
        <th v-for="header in headers" :key="header" @click="sortBy(header)">
          {{ header }}
        </th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="row in sortedRows" :key="row.id">
        <td v-for="value in row" :key="value">
          {{ value }}
        </td>
      </tr>
    </tbody>
  </table>
</template>

<script>
export default {
  props: {
    headers: {
      type: Array,
      required: true
    },
    rows: {
      type: Array,
      required: true
    },
    className: {
      type: String,
      default: 'table'
    }
  },
  data() {
    return {
      sortKey: '',
      sortOrders: {}
    };
  },
  computed: {
    sortedRows() {
      const sortKey = this.sortKey;
      const order = this.sortOrders[sortKey] || 1;
      return this.rows.slice().sort((a, b) => {
        a = a[sortKey];
        b = b[sortKey];
        return (a === b ? 0 : a > b ? 1 : -1) * order;
      });
    }
  },
  created() {
    this.headers.forEach(header => {
      this.sortOrders[header] = 1;
    });
  },
  methods: {
    sortBy(key) {
      this.sortKey = key;
      this.sortOrders[key] = this.sortOrders[key] * -1;
    }
  }
};
</script>

<style>
  table thead {
    position: sticky;
    top: 0;
    background: white;
  }
</style>

This component takes two required props: headers and rows. The headers prop is an array of strings that are used as the header labels, and the rows prop is an array of objects that represent the table rows.

The component also takes an optional className prop that is used as the class name for the table element.

The component sorts the rows based on the header that is clicked, and keeps the header fixed at the top as the user scrolls through the table. The sorting order is reversed each time the same header is clicked again.

This is just one example of a table component with sorting and a fixed header, and you can customize it to suit your specific needs.

Write a table component with sorting and fixed header by Vue + typescript.

<template>
  <table>
    <thead>
      <tr>
        <th v-for="column in columns" @click="sortBy(column.field)" :key="column.field">
          {{ column.label }}
          <i v-if="sortKey === column.field" :class="sortOrders[column.field] > 0 ? 'fa fa-sort-asc' : 'fa fa-sort-desc'"></i>
        </th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="entry in sortedData" :key="entry.id">
        <td v-for="column in columns" :key="column.field">{{ entry[column.field] }}</td>
      </tr>
    </tbody>
  </table>
</template>

<script lang="ts">
import { Component, Prop, Vue } from 'vue-property-decorator';

@Component
export default class TableComponent extends Vue {
  @Prop({ type: Array, default: [] })
  data!: any[];

  @Prop({ type: Array, default: [] })
  columns!: any[];

  sortKey: string = '';
  sortOrders: any = {};

  created() {
    this.columns.forEach(column => {
      this.sortOrders[column.field] = 1;
    });
  }

  sortBy(key: string) {
    this.sortKey = key;
    this.sortOrders[key] = this.sortOrders[key] * -1;
  }

  get sortedData() {
    const sortKey = this.sortKey;
    const order = this.sortOrders[sortKey];
    if (!sortKey) {
      return this.data;
    }

    return this.data.slice().sort((a, b) => {
      a = a[sortKey];
      b = b[sortKey];

      return (a === b ? 0 : a > b ? 1 : -1) * order;
    });
  }
}
</script>

<style>
  th {
    cursor: pointer;
  }

  th, td {
    min-width: 120px;
    padding: 10px;
    text-align: left;
  }

  thead {
    background-color: #eee;
  }

  tbody {
    overflow-y: scroll;
    height: 300px;
  }

  table {
    width: 100%;
  }
</style>

This component takes two props, data and columns, and displays them in a table format. You can sort the data by clicking on the header labels. The table header will be fixed in place when scrolling through the data.

I want to develop a table component by typescript and vue. What should I write in "src/components/table/props.ts" ?

import { PropOptions } from 'vue';

export const TableProps = {
  data: {
    type: Array as () => any[],
    default: () => [],
  },
  columns: {
    type: Array as () => any[],
    default: () => [],
  },
  sortKey: {
    type: String,
    default: '',
  },
  sortOrders: {
    type: Object as PropOptions<Record<string, number>>,
    default: () => ({}),
  },
};

This defines an object TableProps that contains the props for the table component. It includes data, columns, sortKey, and sortOrders. The props data and columns are arrays with default values of an empty array, sortKey is a string with a default value of an empty string, and sortOrders is an object with a default value of an empty object.

Write a table component with sorting and fixed header by Vue + typescript. Use the defineProps function.

<template>
  <table>
    <thead>
      <tr>
        <th v-for="column in columns" @click="sortBy(column.field)" :key="column.field">
          {{ column.label }}
          <i v-if="sortKey === column.field" :class="sortOrders[column.field] > 0 ? 'fa fa-sort-asc' : 'fa fa-sort-desc'"></i>
        </th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="entry in sortedData" :key="entry.id">
        <td v-for="column in columns" :key="column.field">{{ entry[column.field] }}</td>
      </tr>
    </tbody>
  </table>
</template>

<script lang="ts">
import { defineProps, ref, computed, ComponentPublicInstance } from 'vue';

interface Column {
  field: string;
  label: string;
}

interface TableData {
  [key: string]: any;
}

export default {
  props: defineProps({
    data: {
      type: Array as () => TableData[],
      default: () => [],
    },
    columns: {
      type: Array as () => Column[],
      default: () => [],
    },
  }),

  setup(props: Readonly<Record<string, unknown>>, { emit }: ComponentPublicInstance) {
    const sortKey = ref('');
    const sortOrders = ref<Record<string, number>>({});

    const sortedData = computed(() => {
      const data = props.data.slice();
      const order = sortOrders.value[sortKey.value] || 1;

      if (sortKey.value) {
        data.sort((a, b) => {
          a = a[sortKey.value];
          b = b[sortKey.value];

          return (a === b ? 0 : a > b ? 1 : -1) * order;
        });
      }

      return data;
    });

    function sortBy(key: string) {
      sortKey.value = key;
      sortOrders.value[key] = sortOrders.value[key] * -1 || 1;
    }

    return {
      sortKey,
      sortOrders,
      sortedData,
      sortBy,
    };
  },
};
</script>

<style>
  th {
    cursor: pointer;
  }

  th, td {
    min-width: 120px;
    padding: 10px;
    text-align: left;
  }

  thead {
    background-color: #eee;
  }

  tbody {
    overflow-y: scroll;
    height: 300px;
  }

  table {
    width: 100%;
  }
</style>

In this example, the defineProps function is used to define the data and columns props for the table component. The component is set up using the setup function, and the props are accessed through the props parameter.

The ref function is used to create reactive references to the sortKey and sortOrders data properties, and the computed function is used to create a reactive computed property for the sortedData.

The sortBy function is used to update the sortKey and sortOrders properties based on the selected column, and the sorted data is displayed in the table using a v-for directive.

The table header is fixed in place when scrolling through the data using CSS.
