Why transpile LiveScript to JavaScript

Transpiling LiveScript to JavaScript promotes harmony with current web environments and pipelines, simplifies merging into updated systems, and paves the way for ES6 transitions.

Key differences: LiveScript source vs compiled JavaScript

  • LiveScript is brief, relying on spacing and sparse notation
  • JavaScript is straightforward and inherently compatible with all browsers
  • Compilation unfolds LiveScript enhancements into vanilla JavaScript
  • Produced JS can align with ES5, ES6, or subsequent standards
  • LiveScript prioritizes conciseness, JavaScript emphasizes adaptability
  • Troubleshooting benefits from compiled JavaScript in practice

Example 1: Basic function

LiveScript Code

Copy
square = (x) -> x * x
console.log square 5

Converted JS Code

Copy
(function() {
    var square;
    square = function(x) {
        return x * x;
    };
    console.log(square(5));
}).call(this);

Example 2: Class and array mapping

LiveScript Code

Copy
class Person
  constructor: (@name) ->
  greet: -> "Hello #{@name}"

people = ["Alice", "Bob"].map (n) -> new Person n

Converted JS Code

Copy
(function() {
    var Person, people;
    Person = (function() {
        Person.displayName = 'Person';
        var prototype = Person.prototype,
            constructor = Person;
        Person.prototype.constructor = function(name) {
            this.name = name;
        };
        Person.prototype.greet = function() {
            return "Hello " + this.name;
        };

        function Person() {}
        return Person;
    }());
    people = ["Alice", "Bob"].map(function(n) {
        return new Person(n);
    });
}).call(this);

Customization options

The table lists all customization options available to modify your JS output during conversion.

Header False Include the header comment in the output
Indent Size 4 Number of spaces per indent level for beautified output
Indent Char Space Character used for indentation in beautified output
Use Tabs False Indent using tabs instead of spaces
EOL LF End of line character for the output file options include LF, CRLF, and CR
Ending Newline False Add a newline at the end of the output file
Keep Newlines True Preserve existing line breaks from the source
Indent Level 0 Initial indentation depth applied to the entire output
Max Newlines 3 Maximum consecutive line breaks to preserve
Space in parentheses False Add a space inside parentheses when true
Empty parentheses space False Add a space inside empty parentheses when true
Anon function space False Insert a space before parentheses in anonymous functions
Named function space False Insert a space before parentheses in named functions
Brace style collapse Style used for block braces options include collapse expand end expand and none
Break chains False Place each chained method call on a new line
No chain indent False Do not indent chained methods
Keep arrays False Preserve original array formatting
Unescape False Unescape printable xNN strings in the output
Wrap length 0 Wrap lines that exceed this length zero disables wrapping
Comma first False Place commas at the start of lines when true
Operator position before newline Position of operators when wrapping lines options include before newline after newline and preserve original
Indent empty lines False Keep indentation on otherwise empty lines

Best Practices

  • Keep LiveScript files in version control, commit JS only when required
  • Format code during development, minify for production releases
  • Lint transpiled JS before adding it to larger projects
  • Use source maps to debug errors in LiveScript
  • Automate LiveScript to JS conversion with build tools

Conclusion

Employ this LiveScript to ES6 JavaScript transpiler to compile your LS to JS rapidly and securely. Adjust bare mode for precise requirements, select formatting options, and get usable JavaScript instantly.
