Caf.js Core

This repository provides the main Caf.js entry point, creating a framework instance for hosting CAs.

It exports the core packages and an init function that initializes the framework.

For example, in a file called by default ca_methods.js (see methodsFileName property in config file ca.json external:caf_ca to change the name)

const caf = require('caf_core');

exports.methods = {
    async __ca_init__() {
        this.state.counter = 0;
        return [];
    },
    async hello(msg, cb) {
        this.$.log && this.$.log.debug('Got ' + msg);
        this.state.counter = this.state.counter + 1
        return [null, this.state.counter];
    }
};

caf.init(module);

Passing the module argument to caf.init simplifies loading resources with relative paths. For example, to find ca++.json or framework++.json in the same directory as your ca_methods.js file. See external:caf_components for details.

Note that the framework initialization and the methods declaration could be in separate files. It is just convenient to pack them together, and the module caching in require guarantees that we only initialize the framework once.

However, the methods declaration should be in a file named ca_methods.js, unless we configure a different file name, as explained above.
