Package Exports

unassert

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (unassert) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

unassert

Remove assertions from AST to encourage Design by Contract (DbC)

INSTALL

$ npm install --save-dev unassert

EXAMPLE

For given math.js below,

'use strict';

function add (a, b) {
    console.assert(typeof a === 'number');
    assert(!isNaN(a));
    assert.equal(typeof b, 'number');
    assert.ok(!isNaN(b));
    return a + b;
}

Apply unassert then generate modified code to console.

var esprima = require('esprima');
var escodegen = require('escodegen');
var unassert = require('unassert');
var fs = require('fs');
var path = require('path');
var filepath = path.join(__dirname, 'math.js');

var ast = esprima.parse(fs.readFileSync(filepath));
var modifiedAst = unassert(ast);

console.log(escodegen.generate(modifiedAst));

Then you will see assert calls disappear.

'use strict';
function add(a, b) {
    return a + b;
}
