idbfs

This library provides access to the Emscripten file system, including IDBFS. It can be used to manipulate the contents of IDBFS stored by other Emscripten apps.

Versioning

The version number of this package tracks the version of Emscripten used to build it. For example, 6.0.0 is built with Emscripten 6.0.0.

Usage

This is nothing more than an empty Emscripten program compiled with IDBFS enabled, so you can use the Emscripten file system API on it.

Example

The following example reads data.txt in an IDBFS mounted on /idbfs.

const idbfsModule = await import('https://unpkg.com/@irori/idbfs/idbfs.js');
const idbfs = await idbfsModule.default();

idbfs.FS.mkdir('/idbfs');
idbfs.FS.mount(idbfs.IDBFS, {}, '/idbfs');
idbfs.FS.syncfs(true, (err) => {
    if (err) throw err;
    console.log(idbfs.FS.readFile('/idbfs/data.txt', { encoding: 'utf8' }));
});
