Usage

Getting start

import { TextTemplate } from '@master/text-template';

Behaviors of default options

const template = new TextTemplate(text);

equal to

const template = new TextTemplate(text, {
    start: '{{',
    end: '}}',
    behavior: '', // replace
    language: '', // /* data */ /* */,
    removeOnError: false,
    delimiter: ' ',
});

Replace with data tokens

const template = new TextTemplate('Hi {{ username }}');
const renderedText = template.render({ username: 'Aron' });

output renderedText:

Hi Aron

Insert with slot tokens

const html = `
    <title>
        <!-- title --><!-- -->
    <title>
`;
const template = new TextTemplate(html, {
    behavior: 'slot',
    language: 'html'
});
const renderedHtml = template.render({ title: 'Hello World' });

output renderedHtml:

<title>
    <!-- title -->Hello World<!-- -->
<title>

The slot token isn't removed, which means you can keep result and render multiple times.

Combo above behaviors

const readmeText = `
    # Hi {{ username }}
    <!-- description --><!-- -->
`;

const data = {
    username: 'Aron',
    description: 'Hello World {{ username }}'
}

// 1. Insert
const slotTemplate = new TextTemplate(readmeText, {
    behavior: 'slot',
    language: 'readme'
});

// 2. Replace
const template = new TextTemplate(slotTemplate.render(data));

const renderedReadmeText = template.render(data);

output renderedReadmeText:

# Hi Aron
<!-- description -->Hello World Aron<!-- -->

Custom `start` and `end` token

const template = new TextTemplate('Hi ${ username }', {
    start: '${',
    end: '}'
});

Tokenize with js syntax

const data = {
    people:  ['Aron', 'Joy']
}
const text = `/* people.join(' ❤️ ') */ /* */`;
const template = new TextTemplate(text);
const renderedText = template.render(data);

output renderedText

/* people.join(' ❤️ ') */ Aron ❤️ Joy /* */

Remove token when errors occur

removeOnError: true

const text = 'Hi {{ username }}, welcome.';
const data = {};
const t1 = new TextTemplate(text);
const t2 = new TextTemplate(text, { removeOnError: true });
const r1 = t1.render(data);
const r2 = t2.render(data);

output r1

Hi {{ username }}, welcome.

output r2

Hi , welcome.

    behavior: 'slot',
    language: 'html'
});

const template = new TextTemplate(html, {
    behavior: 'slot',
