The package is available in Hex, and can be installed by

[
{:process_store, "~> 0.2.0"}
]
endStore a value:
iex> ProcessStore.store(:my_key, "my value")
nil
# When a key already exists, store the new value and return the previous one.
iex> ProcessStore.store(:my_key, "a new value")
"my value"Fetch a value:
iex> ProcessStore.fetch(:my_key)
"a new value"
iex> ProcessStore.store(:non_existing_key)
nilThe stored values are available in different processes:
iex> ProcessStore.store(:my_key, "my value")
nil
iex> task = Task.async(fn -> ProcessStore.fetch(:my_key) end)
