Test Keplr and LocalOsmosis

Beaker

Beaker is a versatile toolkit that simplifies interactions with CosmWasm smart contracts. It offers project scaffolding, seamless deployment, upgrades, execution, querying, an interactive console, task scripting capabilities and more for a streamlined development experience.

Getting Started

This section is intended to give you an introduction to Beaker, for more detailed reference, you can find them here.

Prerequisites

Rust for building cosmwasm contract
- Rustup for dealing with wasm target
Docker for running wasm rust-optimizer and spinning up LocalOsmosis
Node for frontend related stuffs and beaker-console
- Yarn over NPM, since it will not have package resolving issue and causes weird errors down the road

Installation

Beaker is available via cargo which is a rust toolchain. Once cargo is ready on your machine, run:

cargo install -f beaker # `-f` flag for up-to-date version

Now beaker is ready to use!

Scaffolding your new dapp project

In the directory you want your project to reside, run:

beaker new counter-dapp

This gives you 2 template options to choose from. For the sake of this tutorial, let's use counter-example but you might want to use minimal option in your real work since it has zero assumption about your dapp logic or frontend.

? 🤷   Which starting template would you like to use? ›
  minimal
❯ counter-example

This will generate new directory called counter-dapp which, by default, come from this template.

So what's in the template? Let's have a look...

.
├── frontend
├── contracts
├── Cargo.toml
├── Beaker.toml
├── .gitignore
└── .beaker

`frontend`

This should be self explanatory, it's where frontend and contracts are stored.

With counter-example template, it demonstrate how frontend app can access deployed code/contract's info through .beaker. It does so by symlinking .beaker into frontend directory, and since states in .beaker are in json format, javascript code can just import them.

With minimal template, this directory does not exist, which means it does not assume your frontend choice. In that case, you might want to checkout create-cosmos-app for scaffolding your frontend or just create one from scratch.

`contracts`

This is where smart contracts are stored. Single workspace can contain multiple contracts.

With counter-example template, this should have counter contract pregenerated.

`Cargo.toml`

There is a Cargo.toml here which specifies cargo workspace.

[workspace]

members = [
  'contracts/*',
]

[profile.release]
...

All the crates (rust packages) in contracts directory are included, with unified release profile. With this, when we have to optimize multiple contracts deterministically, we can do that with ease (see Contracts as Workspace Members section in rust-optimizer).

`Beaker.toml`

This is our configuration file, you can find more information about it here.

`.beaker`

Last but not least, .beaker which is the most unusal part. It contains 2 files:

├── state.json
└── state.local.json

These 2 files has similar functionality, which are containing beaker related state such as address, code-id, label for each contract on each network for later use.

While state.json is there for mainnet and testnet state. state.local.json is intended to use locally and being gitignored since its state will not make any sense on other's machine.

And I don't think we have to explain about .gitignore don't we?

Scaffolding new CosmWasm contract

We can scaffold new contract using the following command:

cd counter-dapp
beaker wasm new <contract_name>

Default template is from osmosis-labs/cw-minimal-template

The cw-minimal-template has no logic in it unlike cw-template, only the skeleton is provided, which makes it ideal to start writing new contract.

Now your new contract will be avaiable on contracts/multiplier.

If you want to use other contract template, you can change the configuration, for example:

# Beaker.toml

[wasm]
template_repo = "https://github.com/CosmWasm/cw-template"

This step is not required for the rest of the guide since counter contract is already in place, but you can just try it out.

Deploy contract on LocalOsmosis

LocalOsmosis, as it's name suggest, is Osmosis for local development. In the upcoming release, Beaker will have more complete integration with LocalOsmosis, it has to be installed and run separately.

You can use the osmosis installer and select option 3:

curl -sL https://get.osmosis.zone/install > i.py && python3 i.py

Or if you want to use a specific / modified version of LocalOsmosis, you can build from source by

git clone https://github.com/osmosis-labs/osmosis.git

make localnet-build # build docker image
make localnet-start # docker-compose up

Now, with LocalOsmosis up and running, counter contract can be deployed (build + store-code + instantiate) using the following command:

beaker wasm deploy counter --signer-account test1 --no-wasm-opt --raw '{ "count": 0 }'

What's happending here equivalent to the following command sequence:

# build .wasm file
# stored in `target/wasm32-unknown-unknown/release/<CONTRACT_NAME>.wasm`
# `--no-wasm-opt` is suitable for development, explained below
beaker wasm build --no-wasm-opt

# read .wasm in `target/wasm32-unknown-unknown/release/<CONTRACT_NAME>.wasm` due to `--no-wasm-opt` flag
# use `--signer-account test1` which is predefined.
# The list of all predefined accounts are here: https://github.com/osmosis-labs/LocalOsmosis#accounts
# `code-id` is stored in the beaker state, local by default
beaker wasm store-code counter --signer-account test1 --no-wasm-opt

# instantiate counter contract
# with instantiate msg: '{ "count": 0 }'
beaker wasm instanitate counter --signer-account test1 --raw '{ "count": 0 }'

The flag --no-wasm-opt is skipping rust-optimizer for faster development iteration.

For testnet/mainnet deployment, use:

beaker wasm deploy counter --signer-account <ACCOUNT> --raw '{ "count": 0 }' --network testnet
beaker wasm deploy counter --signer-account <ACCOUNT> --raw '{ "count": 0 }' --network mainnet

Instantiate message can be stored for later use:

mkdir contracts/counter/instantiate-msgs
echo '{ "count": 0 }' > contracts/counter/instantiate-msgs/default.json
beaker wasm deploy counter --signer-account test1 --no-wasm-opt

You can find references for beaker wasm subcommand here.

Contract Upgrade

Contract upgrade in CosmWasm goes through the following steps:

store new code on to the chain
broadcast migrate msg, targeting the contract address that wanted to be upgraded with the newly stored code

To make a contract migratable, the contract needs to have proper entrypoint and admin designated.

To create the contract entrypoint for migration, first, define MigrateMsg in msg.rs, this could have any information you want to pass for migration.

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq, JsonSchema)]
pub struct MigrateMsg {}

With MigrateMsg defined we need to update contract.rs. First update the import from crate::msg to include MigrateMsg:

use crate::msg::{CountResponse, ExecuteMsg, InstantiateMsg, QueryMsg, MigrateMsg};

#[cfg_attr(not(feature = "library"), entry_point)]
pub fn migrate(_deps: DepsMut, _env: Env, _msg: MigrateMsg) -> StdResult<Response> {
    // perform state update or anything neccessary for the migration
    Ok(Response::default())
}

Now deploy the contract with admin assigned

# `--admin signer` use signer address (test1's address in this case) as designated admin
# raw address could be passed in as well
beaker wasm deploy counter --signer-account test1 --no-wasm-opt --raw '{ "count": 0 }' --admin signer

Now try to change the execute logic a bit to see if the upgrade works:

pub fn try_increment(deps: DepsMut) -> Result<Response, ContractError> {
    STATE.update(deps.storage, |mut state| -> Result<_, ContractError> {
        state.count += 1000000000; // 1 -> 1000000000
        Ok(state)
    })?;

    Ok(Response::new().add_attribute("method", "try_increment"))
}

With admin as test1, only test1 can upgrade the contract

beaker wasm upgrade counter --signer-account test1 --raw '{}' --no-wasm-opt

Similar to deploy, upgrade is basiaclly running sequences of commands behind the scene:

beaker wasm build --no-wasm-opt
beaker wasm store-code counter --signer-account test1 --no-wasm-opt
beaker wasm migrate counter --signer-account test1 --raw '{}'

And, like before, --no-wasm-opt only means for developement. For mainnet, use:

beaker wasm upgrade counter --signer-account test1 --raw '{}' --network mainnet

Migrate message can be stored for later use:

mkdir contracts/counter/migrate-msgs
echo '{}' > contracts/counter/migrate-msgs/default.json
beaker wasm upgrade counter --signer-account test1 --no-wasm-opt

You can find more information about their options here.

Execute Contract Messages

Contract messages can be executed using the beaker wasm execute subcommand. For example:

beaker wasm execute counter --raw '{ "increment": {} }' --signer-account test1

Query Contract State

You can query contract state by submitting query messages with the beaker wasm query command. For example:

beaker wasm query counter --raw '{"get_count": {}}'

Signers

Whenever you run command that requires signing transactions, there are 3 options you can reference your private keys:

--signer-account input of this option refer to the accounts defined in the config file, which is not encrypted, so it should be used only for testing
--signer-mnemonic input of this option is the raw mnemonic string to construct a signer
--signer-private-key input of this option is the same as --signer-mnemonic except it expects base64 encoded private key
--signer-keyring use the OS secure store as backend to securely store your key. To manage them, you can find more information here.

Tasks

Sometimes you want to run a series of commands in a single command. For example, you want to deploy a set of contracts that one contract instantiation depends on another contract. You can do this by defining a task in the tasks directory.

beaker task new deploy

This will create a new task file in tasks/deploy.rhai.

Task is written in Rhai which is an embedded scripting language in Rust. You can find example of how to write Rhai here.

Using Rhai as a scripting language makes exposing all existing functionality of Beaker to the task script relatively simple. Currently, all the subcommands of beaker wasm are exposed to the task script. So you can do things like:

let counter_contract = wasm::deploy(merge(
    #{
        signer_account: "test1"
        contract_name: "counter",
        msg: #{}
    }
));

let counter_proxy_contract = wasm::deploy(merge(
    #{
        signer_account: "test1"
        contract_name: "counter",
        msg: #{
            counter_contract_address: counter_contract.address
        }
    }
));

The interface of wasm::deploy the same as the beaker wasm deploy command. Other functions in wasm module are also similar to their corresponding subcommands so you can refer to the documentation for more information about what is avialable in the script.

Note that additional feature here is that msg can also be passed as an object rather than passing JSON string to raw.

There are also some additional helper function and macros that are exposed to the task script.

`fs` module

This module provides access to the file system. It is similar to the std::fs module in Rust. Morre information about the module can be found here. This is how it can be used in the task script:

file = fs::open_file("params.json");

`match_args`

Matching command line arguments passed to the script and returns a map of the arguments

// beaker task run deploy -- --signer test1 --build-flags no_wasm_opt
let cli_args = match_args(["signer", "build_flags"]);

print(cli_args) // => #{ signer: "test1", "build_flags": "no_wasm_opt" }

`merge`

Merges 2 objects together. If there are duplicate keys, the value from the second object will be used.

let a = #{ a: 1, b: 2 };
let b = #{ b: 3, c: 4 };

let merged = merge(a, b);

print(merged) // => #{ a: 1, b: 3, c: 4 }

`@assert`

Perform assertion on the given condition. If the condition is false, the script will exit with an error. This is useful for ensuring that the script is running as expected.

@assert(1 == 1); // pass
@assert(1 == 2); // fail

@assert(1 != 2); // pass
@assert(1 != 1); // fail

@assert(1 < 2); // pass
@assert(1 > 2); // fail

@assert(1 <= 2); // pass
@assert(1 >= 2); // fail

For more example on how to use task, you can refer to the example tasks.

Console

After deployed, you can play with the deployed contract using:

beaker console

It might prompt you like the following:

? Project's Typescript SDK seems to be missing, would you like to generate?

Press enter to proceed for now, and we will discuss about it in detail in the Typescript SDK Generation section.

This will launch custom node repl, where contract, account are available. contract contains deployed contract. account contains pre-defined accounts in localosmosis.

So you can interact with the recently deployed contract like this:

await contract.counter.signer(account.test1).execute({ increment: {} });
await contract.counter.query({ get_count: {} });

You can find avaialable methods for the aforementioned instances here:

You can remove contract and/or account namespace by changing config.

# Beaker.toml

[console]
account_namespace = false
contract_namespace = false

await counter.signer(test1).execute({ increment: {} });
await counter.query({ get_count: {} });

With the Typescript SDK which was previously mentioned, it is used to extend the Contract instance with method generated ftom execute and query messages. For example:

await counter.getCount();

sc = counter.signer(test1); // create signing client for `counter` with `test1`

await sc.increment();
await sc.getCount();

With this, it's more convenient than the previous interaction method since you can use tab completion for the methods as well.

Beaker console is also allowed to deploy contract, so that you don't another terminal tab to do so.

.deploy counter -- --signer-account test1 --raw '{ "count": 999 }'

.build, .storeCode, .instantiate commands are also available and has the same options as Beaker cli command, except that --no-wasm-opt are in by default since it is being intended to use in the development phase.

.help to see all avaiable commands.

Apart from that, in the console, you can access Beaker's state, configuration and sdk from state, conf and sdk variables accordingly.

Typescript SDK Generation

Beaker leverage ts-codegen to generate typescript client for cosmwasm contract. By default, Beaker's template prepare ts/sdk directory where typescript compiler and bundler are setup, so the generated client definition could be used by beaker-console, frontend or published as library for others to use.

To generate sdk for contract, run

beaker wasm ts-gen counter # replace `counter` with any of contract name

With this a package is avaiable in ts/sdk with name <project-name>-sdk which can be used by any node / js / ts project.

The underlying code that actually calls ts-codegen with configuration is located in ts/sdk/scripts/codegen.js.

Let's try adding multiply method to our contract and see how this works.

// msg.rs

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq, JsonSchema)]
#[serde(rename_all = "snake_case")]
pub enum ExecuteMsg {
    Increment {},
    Multiply { times: i32 }, // [1] add this enum variant
    Reset { count: i32 },
}

// contract.rs

#[cfg_attr(not(feature = "library"), entry_point)]
pub fn execute(
    deps: DepsMut,
    _env: Env,
    info: MessageInfo,
    msg: ExecuteMsg,
) -> Result<Response, ContractError> {
    match msg {
        ExecuteMsg::Increment {} => try_increment(deps),
        ExecuteMsg::Multiply { times } => try_multiply(deps, times), // [2] add this match arm
        ExecuteMsg::Reset { count } => try_reset(deps, info, count),
    }
}

// [3] add this function
fn try_multiply(deps: DepsMut, times: i32) -> Result<Response, ContractError> {
    STATE.update(deps.storage, |mut state| -> Result<_, ContractError> {
        state.count *= times;
        Ok(state)
    })?;

    Ok(Response::new().add_attribute("method", "try_multiply"))
}

Then redeploy the contract:

beaker wasm deploy counter --signer-account test1 --no-wasm-opt --raw '{ "count": 0 }'

Then regenerate counter's client

beaker wasm ts-gen counter

Now we can test it out in the beaker console

sc = counter.signer(test1);

await sc.increment();
await sc.getCount();
// => { count: 1 }

await sc.multiply({ times: 2 });
await sc.getCount();
// => { count: 2 }

await sc.multiply({ times: 10 });
await sc.getCount();
// => { count: 20 }

sc is an instance of CounterContract which you can find it in ts/sdk/src/contracts/CounterContract.ts.

Frontend

Beaker project template also come with frontend template. But in order to interact with it you need:

Keplr installed
Keplr chain setup for LocalOsmosis
Add test account to Keplr
- Add account via mnemonic in Keplr. The account test1 can be added by copy-pasting notice oak worry limit wrap speak medal online prefer cluster roof addict wrist behave treat actual wasp year salad speed social layer crew genius to the Import account screen on Keplr. It contains 100,000 test OSMOs.
- List of test accounts and its mnemonics in LocalOsmosis

Now we are good to go! Let's dive in

cd frontend
yarn && yarn dev

Then open http://localhost:3000/ in the browser.

In frontend directory, you will see that .beaker is in here. It is actually symlinked to the one in the root so that frontend code can access beaker state.
