Dependencies

This document provides a reference for the required dependencies when using Telescope-generated code.

Required Dependencies

When using code generated by Telescope, you need to install several CosmJS packages as dependencies:

yarn add @cosmjs/amino @cosmjs/proto-signing @cosmjs/stargate @cosmjs/tendermint-rpc

Or using npm:

npm install @cosmjs/amino @cosmjs/proto-signing @cosmjs/stargate @cosmjs/tendermint-rpc

Core Dependencies

Package	Description	Required For
`@cosmjs/amino`	Implements the Amino encoding format	Amino encoding support, transaction signing
`@cosmjs/proto-signing`	Provides Protobuf-based transaction signing	Direct signing, registry management
`@cosmjs/stargate`	High-level client for interacting with Cosmos SDK chains	Stargate client functionality
`@cosmjs/tendermint-rpc`	Tendermint RPC client implementation	Lower-level blockchain interaction

Optional Dependencies

Depending on which Telescope features you're using, you may need additional dependencies:

If you're using the LCD Client functionality:

yarn add @cosmology/lcd

React Query Integration

If you're using the React Query integration:

yarn add @tanstack/react-query

Vue Query Integration

If you're using the Vue Query integration:

yarn add @tanstack/vue-query

Recoil Integration

If you're using the Recoil state management:

yarn add recoil

Pinia Integration

If you're using the Pinia state management:

yarn add pinia

Mobx Integration

If you're using the Mobx state management:

yarn add mobx mobx-react

CosmWasm Integration

If you're working with CosmWasm contracts:

yarn add @cosmjs/cosmwasm-stargate

Peer Dependencies

The following packages are often used alongside Telescope-generated code but are not strictly required:

Package	Description
`@cosmjs/crypto`	Cryptographic primitives
`@cosmjs/encoding`	Encoding utilities
`@cosmjs/math`	Mathematical utilities, including Decimal type
`@cosmjs/utils`	General utilities

Development Dependencies

When setting up a new project with Telescope, you'll need:

yarn add --dev @cosmology/telescope

Version Compatibility

Ensure that your CosmJS packages have compatible versions. Typically, you should install the same version for all CosmJS packages.

Current recommended CosmJS version:

yarn add @cosmjs/amino@0.31.1 @cosmjs/proto-signing@0.31.1 @cosmjs/stargate@0.31.1 @cosmjs/tendermint-rpc@0.31.1

Example package.json

Here's an example package.json dependencies section for a project using Telescope-generated code with React:
