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.

!
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!
You can get started quickly using our cli
by globally installing via npm:
npm install -g @cosmwasm/ts-codegen
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
},
messageBuilder: {
enabled: false
},
useContractsHooks: {
enabled: false
}
}
}).then(() => {
console.log('✨ all done!');
});
Typescript types and interfaces are generated in separate files so they can be imported into various generated plugins.
option | description |
---|---|
types.enabled |
enable type generation |
types.aliasExecuteMsg |
generate a type alias based on the contract name |
types.aliasEntryPoints |
generate type aliases for the entry points based on the contract name |
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.
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 |
cosmwasm-ts-codegen generate \
--plugin client
--schema ./schema \
--out ./ts \
--name MyContractName
Generate react-query v3 or react-query v4 bindings for your contracts with the react-query
command.
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 |
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
Generate recoil bindings for your contracts with the recoil
command.
cosmwasm-ts-codegen generate \
--plugin recoil \
--schema ./schema \
--out ./ts \
--name MyContractName
option | description |
---|---|
recoil.enabled |
enable the recoil plugin |
Generate pure message objects with the proper utf8
encoding and typeUrl
configured that you can broadcast yourself via cosmjs
with the message-composer
command.
cosmwasm-ts-codegen generate \
--plugin message-composer \
--schema ./schema \
--out ./ts \
--name MyContractName
option | description |
---|---|
messageComposer.enabled |
enable the messageComposer plugin |
Generate raw message jsons for use in your application with the message-builder
command.
cosmwasm-ts-codegen generate \
--plugin message-builder \
--schema ./schema \
--out ./ts \
--name MyContractName
option | description |
---|---|
messageBuilder.enabled |
enable the messageBuilder plugin |
option | description |
---|---|
useContractsHooks.enabled |
enable the useContracts plugin |
import { useChain } from '@cosmos-kit/react';
import { ContractsProvider } from '../path/to/codegen/contracts-context';
export default function YourComponent() {
const {
address,
getCosmWasmClient,
getSigningCosmWasmClient
} = useChain(chainName);
return (
<ContractsProvider
contractsConfig={{
address,
getCosmWasmClient,
getSigningCosmWasmClient,
}}
>
<SomeCoolComponent />
</ContractsProvider>
)
};
If you're using Babel, please make sure include '@babel/preset-react'
in devDeps and presets in .babelrc.js
:
presets: [
'@babel/typescript',
'@babel/env',
'@babel/preset-react',
]
For tsc
, you should set the jsx
option to 'react'
in your tsconfig.json
.
Once enabled, you can get contracts very simply:
const { marketplace } = useContracts();
const marketplaceClient = marketplace.signingClient(marketplaceContract);
await marketplaceClient.updateAskPrice({
collection: token.collectionAddr,
price: {
amount,
denom,
},
tokenId,
});
The bundler will make a nice package of all your contracts. For example:
const {
MinterQueryClient,
useMinterConfigQuery
} = contracts.Minter;
const { CwAdminFactoryClient } = contracts.CwAdminFactory;
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 |
| option | description | default |
| --------------------- | ---------------------------------------------- |
| useShorthandCtor
| Enable using shorthand constructor. | true |
Using shorthand constructor (Might not be transpiled correctly with babel):
constructor(
protected address: string | undefined,
protected cosmWasmClient: CosmWasmClient | undefined,
protected signingCosmWasmClient: SigningCosmWasmClient | undefined,
private TSign?: new (
client: SigningCosmWasmClient,
sender: string,
contractAddress: string
) => TSign,
private TQuery?: new (
client: CosmWasmClient,
contractAddress: string
) => TQuery,
private TMsgComposer?: new (
sender: string,
contractAddress: string
) => TMsgComposer
) {}
Without using shorthand constructor:
address: string | undefined;
...
TMsgComposer?: new (
sender: string,
contractAddress: string
) => TMsgComposer;
constructor(
address: string | undefined,
...
TMsgComposer?: new (
sender: string,
contractAddress: string
) => TMsgComposer
) {
this.address = address;
...
this.TMsgComposer = TMsgComposer;
}
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.
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
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
If needed, you can generate only the types with the typesOnly
option;
cosmwasm-ts-codegen generate \
--typesOnly \
--schema ./schema \
--out ./ts \
--name SG721
for lower-level access, you can import the various plugins directly:
import {
generateTypes,
generateClient,
generateReactQuery,
generateRecoil,
generateMessageComposer
} from '@cosmwasm/ts-codegen';
cosmwasm-ts-codegen generate --typesOnly

We generate code from the JSON Schema exported from CosmWasm smart contracts.
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
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,
}
}
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",
);
yarn
yarn bootstrap
yarn build
Then cd
into a package and run the tests
cd ./packages/wasm-ast-types
yarn test:watch
See the docs in the wasm-ast-types
package.
