Embedding the NATS server the right way

[maxpert]

Hey folks I've been struggling to embed NATS into my open source project. Here is code on how I am embedding NATs into Marmot. Now when I supply configuration file:

accounts: {
    STREAMERS: {
        jetstream: enabled
        users: [
            {user: marmot, password: PassW0rd12345}
        ]
    },
    SYS: {
        users: [
            {user: admin, password: PassW0rd123}
        ]
    },
}
system_account: SYS

cluster {
  name: we4u
  listen: localhost:4248
  routes = []
}

jetstream: enabled
jetstream {
    store_dir: "/tmp/nats1/stream"
    max_mem: 32M
    max_file: 1G
}

Launching server I get error:

Here is what I want Marmot to be able to do:

• Launch a node with a NATS server as primary node
• Add nodes to cluster that can have cluster peers
• For quick start no NATs configuration and sane defaults so that I can pass only cluster address for primary and peer nodes as part of CLI. People can later use configuration file later to do more complex configurations.

I am looking for expertise here to help me make NATs part of Marmot and really easy to get up and running while allowing complex configurations via nats config file if required.
