Running the node template

caution

We are now working in the node's root directory (substrate-mooc-node), not the pallet directory.

With all of our functionality in place, it is finally time to run and view our node running in an actual environment.

Running tests​

Before running, it is a good idea to run tests to make sure everything is working as it should:

cargo test

Launching the node​

If the tests pass, you may now launch the node. Ensure you are in the root directory of the node:

info

Note that we are running in dev mode, meaning our node has finalization without needing another node to run.

cargo run -- --dev

This may take some time to build and run. Once it does, you should see the following output:
