@cosmwasm/ts-codegen

Generate TypeScript SDKs for your CosmWasm smart contracts

npm install -g @cosmwasm/ts-codegen

The quickest and easiest way to interact with CosmWasm Contracts. @cosmwasm/ts-codegen converts your CosmWasm smart contracts into dev-friendly TypeScript classes so you can focus on shipping code.

🎥 Checkout our video playlist to learn how to use ts-codegen!

Quickstart

Clone your project and cd into your contracts folder

git clone https://github.com/public-awesome/launchpad.git
cd launchpad/contracts/sg721-base/

Run cosmwasm-ts-codegen to generate your code.

cosmwasm-ts-codegen generate \
          --plugin client \
          --schema ./schema \
          --out ./ts \
          --name SG721 \
          --no-bundle

The output will be in the folder specified by --out, enjoy!

Usage

You can get started quickly using our cli by globally installing via npm:

npm install -g @cosmwasm/ts-codegen

Programmatic Usage

For production usage, we recommend setting up a build script that uses the main entry point:

import codegen from '@cosmwasm/ts-codegen';

codegen({
  contracts: [
    {
      name: 'SG721',
      dir: './path/to/sg721/schema'
    },
    {
      name: 'Minter',
      dir: './path/to/Minter/schema'
    }
  ],
  outPath: './path/to/code/src/',

  // options are completely optional ;)
  options: {
    bundle: {
      bundleFile: 'index.ts',
      scope: 'contracts'
    },
    types: {
      enabled: true
    },
    client: {
      enabled: true
    },
    reactQuery: {
      enabled: true,
      optionalClient: true,
      version: 'v4',
      mutations: true,
      queryKeys: true,
      queryFactory: true,
    },
    recoil: {
      enabled: false
    },
    messageComposer: {
      enabled: false
    },
    msgBuilder: {
      enabled: false
    }
  }
}).then(() => {
  console.log('✨ all done!');
});

Types

Typescript types and interfaces are generated in separate files so they can be imported into various generated plugins.

see example output code

Types Options

option	description
`types.enabled`	enable type generation
`types.aliasExecuteMsg`	generate a type alias based on the contract name

Client

The client plugin will generate TS client classes for your contracts. This option generates a QueryClient for queries as well as a Client for queries and mutations.

see example output code

Client Options

option	description
`client.enabled`	generate TS client classes for your contracts
`client.execExtendsQuery`	execute should extend query message clients
`client.noImplicitOverride`	should match your tsconfig noImplicitOverride option

Client via CLI

cosmwasm-ts-codegen generate \
    --plugin client
    --schema ./schema \
    --out ./ts \
    --name MyContractName

React Query

Generate react-query v3 or react-query v4 bindings for your contracts with the react-query command.

see example output code

React Query Options

option	description
`reactQuery.enabled`	enable the react-query plugin
`reactQuery.optionalClient`	allows contract client to be undefined as the component renders
`reactQuery.queryKeys`	generates a const queryKeys object for use with invalidations and set values
`reactQuery.queryFactory`	generates a const queryFactory object for useQueries and prefetchQueries use
`reactQuery.version`	`v4` uses `@tanstack/react-query` and `v3` uses `react-query`
`reactQuery.mutations`	also generate mutations
`reactQuery.camelize`	use camelCase style for property names

React Query via CLI

Here is an example without optional client, using v3 for react-query, without mutations:

cosmwasm-ts-codegen generate \
    --plugin client \
    --plugin react-query \
    --schema ./schema \
    --out ./ts \
    --name MyContractName \
    --version v3 \
    --no-optionalClient \
    --no-mutations

Example with optional client, using v4, with mutations:

cosmwasm-ts-codegen generate \
    --plugin react-query \
    --schema ./schema \
    --out ./ts \
    --name MyContractName \
    --optionalClient \
    --version v4 \
    --mutations

Recoil

Generate recoil bindings for your contracts with the recoil command.

see example output code

Recoil via CLI

cosmwasm-ts-codegen generate \
    --plugin recoil \
    --schema ./schema \
    --out ./ts \
    --name MyContractName

Recoil Options

option	description
`recoil.enabled`	enable the recoil plugin

Message Composer

Generate pure message objects with the proper utf8 encoding and typeUrl configured that you can broadcast yourself via cosmjs with the message-composer command.

see example output code

Message Composer via CLI

cosmwasm-ts-codegen generate \
    --plugin message-composer \
    --schema ./schema \
    --out ./ts \
    --name MyContractName

Message Composer Options

option	description
`messageComposer.enabled`	enable the messageComposer plugin

Msg Builder

Generate raw message jsons for use in your application with the msg-builder command.

see example output code

Msg Builder via CLI

cosmwasm-ts-codegen generate \
    --plugin msg-builder \
    --schema ./schema \
    --out ./ts \
    --name MyContractName

Message Composer Options

| option | description | -------------| ------------------------------ | ------------------------------------------------------------------- | | msgBuilder.enabled | enable the msgBilder plugin |

Bundles

The bundler will make a nice package of all your contracts. For example:

const {
  MinterQueryClient,
  useMinterConfigQuery
} = contracts.Minter;

const { CwAdminFactoryClient } = contracts.CwAdminFactory;

Bundler Options

option	description
`bundle.enabled`	enable the bundler plugin
`bundle.scope`	name of the scope, defaults to `contracts` (you can use `.` to make more scopes)
`bundle.bundleFile`	name of the bundle file

CLI Usage and Examples

Interactive prompt

The CLI is interactive, and if you don't specify an option, it will interactively prompt you.

cosmwasm-ts-codegen generate
? [plugin] which plugins? (Press <space> to select, <a> to toggle all, <i> to invert selection)
❯◯ client
 ◯ recoil
 ◯ react-query
 ◯ message-composer

In this example, you can press space bar to select a number of plugins you wish you enable.

Specifying Plugins

Additionally, it will also show you the name of the field (in this case plugin) so you can specify the parameter (for example when using CI/CD) on the comand line. Here is an exampl with --plugin set to client via CLI:

cosmwasm-ts-codegen generate \
    --plugin client
    --schema ./schema \
    --out ./ts \
    --name MyContractName

You can specify multiple --plugin options using the generate command:

cosmwasm-ts-codegen generate \
          --plugin client \
          --plugin recoil \
          --schema ./schema \
          --out ./ts \
          --name SG721

Bypassing the Prompt

All options can be provided so you can bypass the prompt.

For confirm options, you can pass --no-<name> to set the value to false. Here is an example without optional client, using v3 for react-query, without mutations:

cosmwasm-ts-codegen generate \
    --plugin client \
    --plugin react-query \
    --schema ./schema \
    --out ./ts \
    --name MyContractName \
    --version v3 \
    --no-optionalClient \
    --no-mutations

Example with optional client, using v4, with mutations:

cosmwasm-ts-codegen generate \
    --plugin react-query \
    --schema ./schema \
    --out ./ts \
    --name MyContractName \
    --optionalClient \
    --version v4 \
    --mutations

Types Only Option

If needed, you can generate only the types with the typesOnly option;

cosmwasm-ts-codegen generate \
          --typesOnly \
          --schema ./schema \
          --out ./ts \
          --name SG721

Advanced Usage

for lower-level access, you can import the various plugins directly:

import { 
  generateTypes,
  generateClient,
  generateReactQuery,
  generateRecoil,
  generateMessageComposer,
} from '@cosmwasm/ts-codegen';

Example Output

cosmwasm-ts-codegen generate --typesOnly

JSON Schema

We generate code from the JSON Schema exported from CosmWasm smart contracts.

JSON Schema Generation

Currently you have to have the JSON Schema output. Here is an example to start.

First, get the Rust contracts and run cargo build:

git clone [email protected]:public-awesome/stargaze-contracts.git
cd stargaze-contracts
cargo build

now build the schema with cargo schema

cd contracts/sg721/
cargo schema

Exporting Schemas

`cosmwasm v1.1` Example

Using the new write_api method, you can export schemas:

use cosmwasm_schema::write_api;

use cw4_group::msg::{ExecuteMsg, InstantiateMsg, QueryMsg};

fn main() {
    write_api! {
        instantiate: InstantiateMsg,
        execute: ExecuteMsg,
        query: QueryMsg,
    }
}

`cosmwasm_std` Example

Here is a legacy example:

use cosmwasm_std::{Addr, CosmosMsg, Empty};

export_schema_with_title(&schema_for!(MinterData), &out_dir, "MinterResponse");
export_schema_with_title(&schema_for!(Addr), &out_dir, "StakingResponse");
export_schema_with_title(&schema_for!(Addr), &out_dir, "DaoResponse");
export_schema_with_title(
      &schema_for!(CosmosMsg<Empty>),
      &out_dir,
      "CosmosMsg_for_Empty",
);
