@mappedin/mvf

A starting point for interacting with MVF bundles. For Developers looking to get up and running with MVF, this is likely the best starting point.

Default Parser

For most developers, the createMVFv3Parser function and associated type MVFv3 are what should be used. This provides an exporter parser, and a type for the parsed data for convenience.

import { createMVFv3Parser, type MVFv3 } from '@mappedin/mvf';

const parser = createMVFv3Parser().build().unwrap();

const myFunction = (data: MVFv3) => {
	// do something with the parsed data.
}

const mvf: MVFv3 = await parser.decompress(data).then((result) => result.unwrap());
const result = myFunction(data);
Copy

Note the use of .unwrap() on the result of some functions. As implemented, these APIs are guaranteed not to throw, but as a result the returned value must be transformed in some way to interact with it. Unwrapping a value essentially restores "default" Javascript behaviour and throw an exception if there was an error while performing the operation.

For more information on the parser API, see the MVFParser docs.

CMS Parser

For developers who have map data stored in Mappedin CMS, an additional parser preset is exposed to fit the format of that data.

import { createCMSMVFv3Parser, type CMSMVFv3 } from '@mappedin/mvf/preset-cms';
Copy

Otherwise, usage is the same as described above.
