The Particle Binary Version Reader!
If you're building firmware on the Particle Platform, you might be curious to see the metadata stored in your firmware! This module will read any metadata stored in the various modules (bootloader, system, user), and help you understand any dependencies.
Usage
const Reader = require('binary-version-reader').HalModuleParser;
const reader = new Reader();
reader.parseFile('your_binary.bin', function(fileInfo, err) {
console.log(fileInfo);
});You can also get the raw output of binary-version-reader by using it as a command line tool without installing it.
npx binary-version-reader your_binary.bin
Example output

}Testing firmware binaries
When you need to create a firmware binary for an integration test, you
can use the provided firmwareTestHelper instead of relying on fixtures
in your application.
const { firmwareTestHelper, ModuleInfo } = require('binary-version-reader');
const binary = firmwareTestHelper.createFirmwareBinary({ productId: 123, productVersion: 6, platformId: 10, deps: [ { func: ModuleInfo.FunctionType.SYSTEM_PART, index: 1, version: 1210 } ] });
