vf-to-ubf Module

This module is responsible for converting any Voiceflow (.vf) file to its respective representation in the Universal Bot Format. It is written as an independent and self-contained npm package.

Schema Validation

We must guarantee that we interpret the Voiceflow format correctly. That is, if anything in the format changes - even a seemingly innocent extra metadata key - we must not proceed with that input until the conversion software is updated to work with the new format. This way we can guarantee that if the package does not throw an exception, its input has been interpreted correctly.

We achieve this by defining a JSON Schema for the Voiceflow format. This way, we can guarantee that if the input matches the schema, then it must be supported, by definition.

Usage Example

import {voiceflowToBotFormat} from 'vf-to-ubf';
var fs = require('fs');

diagram = fs.readFileSync("./VoiceflowFile.vf")

universal_format = voiceflowToBotFormat(diagram)
