Remote Targets

Effects in Jix are always created within a target context that specifies the host and user they apply to. This allows for managing installations across different machines. The target context is automatically set when using Host.install() or User.install() methods, and effects created within these contexts can access information about the target host and user.

const vps1 = new jix.Host("10.200.200.1", { alice: {} })

let hellojix = () => jix.script`
  Hello from ${jix.target().host.hostname}!
`

export const install = () => {
  // Here, jix.target().host === Host("localhost")
  vps1.install(host => {
    // Here, jix.target().host === vps1 === host
    // and   jix.target().user.name === "root"
    jix.alias({ hellojix })  
    // makes hellojix available in ssh root@10.200.200.1

    host.users.alice.install(user => {
      // Here jix.target().user.name === "alice"
      jix.alias({ hellojix })
      // makes hellojix available in ssh alice@10.200.200.1
    })
  })
}
