tpl2

Replace the placeholder string with real data(e.g. url params,timestamp/version of copyright)

1, tpl2(templateString, dataSource)

• templateString:

Use double braces wrap the field that you want to replace,like {{field}}. Then tpl2 will replace {{field}} with the value of dataSource, value = dataSource[field].

• dataSource:

The dataSource is a tipical k-v Object

2, Sample

    const tpl2 = require('tpl2')
    const template = 'this is an example, published at {{timestamp}}'
    const dataSource = {
        timestamp: Date.now()
    }
    const newString = tpl2(template, dataSource);
    console.log(newString)
    //newString === 'this is an example, published at 1507889438310'

3, If you wanna keep the double braces, use backslash \

    
    const template = 'the \\{\\{field\\}\\} wont be replaced by the dataSouce\'s field value'
    const dataSource = {
        field: "test_text"
    }
    const newString = tpl2(template, dataSource)
    console.log(newString)
    //newString === 'the {{field}} wont be replaced by the dataSouce's field value'

4, \\ => \

The Unicode for \ is \u005c

    var s = 'the double backslashes "\\\\"'; // or var s = 'the double backslashes \u005c\u005c'
    console.log(tpl2(s, {}));
    //console panel will see: 
    //>> the double backslashes "\"
