<big>Cardano JS SDK</big> <img width="200" src=".github/images/cardano-logo.png"/> [![PostIntegration][img_src_post-integration]][workflow_post-integration] [![Release][img_src_release]][workflow_release] <hr/> ## Overview A suite of TypeScript packages suitable for both Node.js and browser-based development. - [@cardano-sdk/core](./packages/core) - [@cardano-sdk/crypto](./packages/crypto) - [@cardano-sdk/input-selection](./packages/input-selection) - [@cardano-sdk/dapp-connector](./packages/dapp-connector) - [@cardano-sdk/governance](./packages/governance) - [@cardano-sdk/key-management](./packages/key-management) - [@cardano-sdk/web-extension](./packages/web-extension) - [@cardano-sdk/wallet](./packages/wallet) - [@cardano-sdk/projection](./packages/projection) - [@cardano-sdk/util-rxjs](./packages/util-rxjs) - [@cardano-sdk/util](./packages/util) - [@cardano-sdk/util-dev](./packages/util-dev) - [@cardano-sdk/cardano-services](./packages/cardano-services) - [@cardano-sdk/cardano-services-client](./packages/cardano-services-client) ### Supported Environments Packages are distributed as both CommonJS and ESM modules. - Node.js >=22 - Browser via bundlers (see [example webpack config](./packages/e2e/test/web-extension/webpack.config.js)) ### Getting Started The [GETTING_STARTED](./GETTING_STARTED.md) guide provides a quick way to start experimenting. ### Testing - [@cardano-sdk/golden-test-generator](./packages/golden-test-generator) ## Development A Yarn Workspace maintaining a single version across all packages. #### System Requirements - [nvm](https://github.com/nvm-sh/nvm) - [yarn](https://yarnpkg.com/getting-started/install) - [Node.js](https://nodejs.org/en/download) 22 or later - [Docker Desktop] 3.4 or later or a Docker installation that includes Compose V2 #### Clone ```bash git clone \ https://github.com/input-output-hk/cardano-js-sdk.git \ && cd cardano-js-sdk ``` #### Install and Build ```bash nvm install && \ nvm use && \ DETECT_CHROMEDRIVER_VERSION=true yarn global add chromedriver && \ yarn install && \ yarn build ``` The web extension e2e tests uses [chromedriver](https://www.npmjs.com/package/chromedriver). `chromedriver` and your Chrome browser versions should match, if they don’t the driver will error. If you have issues, try running `yarn workspace @cardano-sdk/e2e remove chromedriver && yarn workspace @cardano-sdk/e2e add chromedriver` to reinstall the latest version. #### Run Tests ```bash yarn test ``` or ```bash yarn test:debug ``` #### Hardware Testing For hardware wallet testing, see [Hardware Testing Guide](packages/wallet/HARDWARE_TESTING.md). ### Lint ```bash yarn lint yarn lint --fix ``` ### Cleanup ``` yarn cleanup ``` ### Update Cardano configuration subrepo #### With `yarn` Requires [git-subrepo](https://github.com/git-commands/git-subrepo) to be installed. ``` yarn config:update ``` ## Get CBOR representation of an on chain transaction Once we have a [running network](packages/cardano-services/README.md#production) synced at least up to the block containing the transaction we are interested in, issue following command to get the CBOR representation of the transaction. ``` yarn tx-cbor <txId> ``` This works regardless of the local ports configuration through environment variables. ## Distribute ### Pack ```bash ./scripts/pack.sh ``` ### Publish to npm.org ```bash ./scripts/publish.sh ``` ### Generate Docs ```bash yarn docs ``` <a href="https://input-output-hk.github.io/cardano-js-sdk">:book: Documentation</a> [img_src_post-integration]: https://github.com/input-output-hk/cardano-js-sdk/actions/workflows/post_integration.yml/badge.svg [workflow_post-integration]: https://github.com/input-output-hk/cardano-js-sdk/actions/workflows/post_integration.yml [img_src_release]: https://github.com/input-output-hk/cardano-js-sdk/actions/workflows/release.yaml/badge.svg [workflow_release]: https://github.com/input-output-hk/cardano-js-sdk/actions/workflows/release.yaml [docker desktop]: https://docs.docker.com/desktop/ [let us know!]: https://github.com/input-output-hk/cardano-graphql/discussions/new
