Avail Hafif İstemcisi Nasıl Çalıştırılır?

This guide outlines how to set up an Avail light client. You can either:

  1. Run the light client on an existing network
  2. Run the light client locally

Latest release​

You can find the latest release binary in the avail-light repository.

RepositoryLatest Release
avail-lightv1.7.4

Run on an Existing Network​

In this example, you will download the light client and connect to an existing public network.

  1. Download the latest Avail light client release. The light client is available pre-built for different architectures.

  2. If you prefer building the light client yourself, see build the Avail light client from source.

  3. Run the light client with the following pre-defined configuration file:

./avail-light --network goldberg
  1. If you want to supply your own configuration file, use:
./avail-light --config config.yaml --network goldberg

That's it 🎉! You have successfully run the light client and connected to a public network. The light client should show output similar to the following:

Sample output

The client output should look like this:

Run Locally​

If you want to connect the Avail light client to a local network, you will need to run your own Avail node and your own Avail light client bootstrap node.

  1. Run the Avail node. For local set-up, run the node in dev mode:

    ./data-avail --dev

  2. Run a bootstrap node.

  3. Once the bootstrap node is running, use the following command to run your client:

    ./avail-light --network local

  4. If you want to supply your own configuration file, use:

    ./avail-light --config config.yaml --network local

Build From Source​

You can build the light client directly from source.

git clone https://github.com/availproject/avail-light.git
cd avail-light
cargo build --release

Find the resulting avail-light binary in the target/release directory.

Next Steps​

Run a Relay node​

We provide an Avail light client relay node that can help you with running your light client from behing NAT and firewalls. Find more information on running a relay node here.

Run a Full Node​

Consider running a full node by following the deployment guide here.
