Welcome to the Go to Gno Builder Challenge. The Challenge is to write the Memeland package from scratch.
Check out the sections below to get started.
All needed tools can be found in the Gno monorepo.
First, clone the monorepo:
git clone git@github.com:gnolang/gno.gitNext, install all the necessary binaries:
gno- binary for running & testing the Gno language, found ingnovm/. Run
cd gnovm
make build && make install
gnoland- binary containing the node which opens up an RPC API, found ingno.land/
cd gno.land
make build && make install
gnodev- a tool to help you develop Gno apps faster
make install.gnodev
The
install.gnodevcommand can be found in the root Makefile.
In the api/p/memeland folder you will be able to find the
template package file, as well
as tests that should be passing when you are done with the Challenge.
To start tests, run gno test . -v in the api/p/memeland folder. You should
get the following output before starting:
❯ gno test . -v
=== RUN TestPostMeme
panic: implement me
--- FAIL: TestPostMeme (0.00s)

=== RUN TestUpvote

Memeland comes with a pre-built UI, which can be found in theui/
folder. Once you have implemented all the needed functions in the Memeland package,
you can fully run your version of Memeland.
gnodev is a tool that will deploy your Gno code to a local gno.land node,
and expose an RPC endpoint for the UI to connect to it. Start gnodev, giving
it the paths to the Memeland package and realm folders:
gnodev ./api/p/memeland ./api/r/memeland
Then, in the ui/ folder:
- Install all necessary dependencies with
yarn, - make a
.envfile from the.env.example, - run
yarn devto start a vite server for your UI
To connect and interact with the Memeland app, you need to install the Adena wallet. After installing Adena, create a new account with the following mnemonic:
source bonus chronic canvas draft south burst lottery vacant surface solve popular case indicate oppose farm nothing bullet exhibit title speed wink action roast
After completing this step, you will be able to interact with the Memeland app.
Congratulations! You've completed the Go to Gno Builder Challenge!
