Requiring Files

In the Quick Design Calculator, you can import files from both the json and utils directories into calculate.js. This encourages code reusability and helps maintain large calculation packs. The required folder structure is shown in the image below.

Requiring JSON Files

In the Quick Design Calculator, you can import files from both the json and utils directories into calculate.js. This encourages code reusability and helps maintain large calculation packs.

Files in the json directory must have the .json extension. These files can be required in calculate.js using the global requireJSON(filename) function.

The required folder structure is shown in the image below.

Import Example

// Returns JSON data

const data = requireJSON('data.json');

Requiring JavaScript Files

Files in the utils directory must have a .js extension. They can be required in calculate.js using the global requireUtil(filename) function. To be executable in calculate.js, they must export functions using module.exports.

Export Example

module.exports = {

'foo': function (bar) {

return bar.toLowerCase();

}

}

Import Example

const utils = requireUtil('util.js');

const res = utils.foo("TEST") // returns test

Mutliple Directories

const nested_utils = requireUtil('/bar/util.js');

const res = nested_utils.foo("TEST") // returns test

Requiring CSV Files

Files in the csv directory must have the .csv extension. These files can be required in calculate.js using the global requireCSV(filename) function. The returned CSV string can then be parsed using the CSV helper functions.

Import Example

const csv = requireCSV('test.csv');

// Parse into a flat array of objects

const data = CSV.csvToJSON(csv, true);

// Parse into a nested object using the first 3 columns as selector keys

const data2 = CSV.csvToNestedJSON(csv, true, 3, ",", false);
