webidl-conversions 7.0.0

WebIDL-conversions is a utility package that implements the algorithms for converting to and from JavaScript values as described in the Web IDL (Web Interface Definition Language). The package handles various data types such as 'any', 'undefined', 'boolean', integer types, 'float', 'double', 'DOMString', 'ByteString', 'USVString', 'object', and 'BufferSource', among others. The package allows writing functions in JavaScript that behave like a given Web IDL operation, adhering to the concept of converting JavaScript values to Web IDL values and back to JavaScript values, effectively emulating the conversion pipeline.

To use webidl-conversions, you need to install the package via npm and import it into your project. It exposes a variety of methods for each Web IDL type, which allows the conversion of JavaScript values according to the rules set by Web IDL. Here is an example of how you might implement it:

"use strict";
const conversions = require("webidl-conversions");

function myFunction(x, y) {
    x = conversions["boolean"](x);
    y = conversions["unsigned long"](y);
    // additional code here
}

In the example above, the variables x and y are converted to Boolean and Unsigned Long types, respectively, as per the Web IDL. Each method could throw an error if the Web IDL specifies to do so.

The documentation for the webidl-conversions package can be found on the GitHub repository. It provides in-depth specifics about the API, implemented conversions, notes on certain types, background information, and cautions for utilization. The documentation is important for understanding the restrictions, usage scenarios, and the conceptual workings of the package. It is advisable to read the documentation to fully harness the functionalities of the package and understand its limitations.
