Javascript Support

Option 1: Run a Javascript file via filter

JS Result : {{"./test.js" | jseval }}

Where './test.js' is:

exports.default = function (engine) {
    console.log('hello');
    return 'cool!';
}

Output

JS Result : cool!

Remarks

• Paths are resolved via Liquid standard options options.root where './test.js' is being appended to any of the roots listed in options.root

Option 2: Run a Javascript expression

JS Expression Result : {{"2+2 + someNumber" | jsexp }}

Output

JS Expression Result : 6

Remarks

• someNumber is being added to the expression in top as standard variable, using the Liquid parse option arguments, eg :

const template_ = read(`${machine_path}/templates/site/test-js.html`) as string;

let vars = {
    name: '{{test}}',
    test: '{{other}}',
    other: 'alice',
    show: false,
    someNumber: 2
};

let options = {
    root: [
        `${machine_path}/`,
        `${machine_path}/templates/site/`,
        `${machine_path}/templates/shared/`
    ],
    toHTML: false
}

let e = new Engine(options);
e.parse(template_, vars, 5).then(console.log);

return;
