string-format-jsx v1.0.0

string-format-jsx

A lightweight and framework-independent library for template string interpolation similar to JSX elements.

Install

pnpm add string-format-jsx

Usage

Core

Use with any framework

import { formatElements } from 'string-format-jsx';

formatElements('Hello, <a>@u3u</a>', {
  createElement: (type, props, children) => yourFramework.createElement(type, props, children),
});

React

Use the entrance of React.createElement by default

!TIP

The formatElements is only used for replacing JSX elements and does not include string interpolation functionality. You can use it together with the built-in interpolation function or any other interpolation library.

import { formatElements } from 'string-format-jsx/react';

const result = formatElements('Hello, <a>@u3u</a>', {
  components: {
    a: (children) => <Link>{children}</Link>,
  },
});

Trans Component (React)

Use interpolation and formatElements together.

import { Trans } from 'string-format-jsx/trans';

const result = (
  <Trans
    components={{
      a: (children, key) => {
        return (
          <a
            className="text-primary-500 hover:text-primary-400 transition"
            key={key}
            onClick={() => {
              console.log(children);
            }}
          >
            {children}
          </a>
        );
      },

      b: (children, key) => {
        return (
          <b className="font-medium" key={key}>
            {children}
          </b>
        );
      },
    }}
    text={dedent`
      Hello, <a>The number is <b>{count}</b></a>
      <br />
      The number is <b>{count}</b>.
    `}
    values={{
      count: 10,
    }}
  />
);

Interpolation

Built-in support for simple string templates interpolation, you can use any other string interpolation library.

import { interpolation } from 'string-format-jsx';

const result = interpolation('Hello, {name} ({count})', {
  values: {
    count: 0,
    name: 'u3u',
  },
});

Examples

Vue2

import { formatElements, interpolation } from 'string-format-jsx';

export const Trans = {
  functional: true,

  name: 'Trans',

  props: {
    tag: { default: 'span', type: [String, Object, Function] },
    text: String,
    values: Object,
  },

  render: (h, { data, props, scopedSlots: slots }) => {
    const { tag, text, values } = props;

    return h(
      tag,
      data,
      formatElements(interpolation(text, { values }), {
        components: slots,
        createElement: h,
      }),
    );
  },
};

const vnode = (
  <Trans
    scopedSlots={{
      a: (children) => {
        return (
          <a
            class="cursor-pointer text-primary hover:text-primary-400"
            onClick={() => {
              console.log(children);
            }}
          >
            {children}
          </a>
        );
      },

      b: (children) => <b class="font-medium">{children}</b>,
    }}
    text={dedent`
      Hello, <a>The number is <b>{count}</b></a>
      <br />
      The number is <b>{count}</b>.
    `}
    values={{ count: 10 }}
  />
);
