Installing Library Package

Add package to your project Mixfile:

The library package can be installed by adding event_bus to your list of dependencies in mix.exs file:

def deps do
  [
     # ...,
     {:event_bus, "~> 1.6.0"}
  ]
end

Fetch the package as usual

In your project's root directory, run mix deps.get shell command to fetch the library from hex packages. On successful fetch you will see an output like:

Resolving Hex dependencies...
Dependency resolution completed:
New:
  event_bus 1.6.0
* Getting event_bus (Hex package)

Start the event_bus app before your app

Add :event_bus to your mix.exs file's application/0 function inside the applications list:

def application do
  [
    applications: [
      # ...,
      :event_bus
    ]
  ]
end

Congratulations!!! You have successfully installed the event_bus library. The next step is defining and creating the topic names which will be used in your project.
