Installation

Install GLIN SDK for your preferred language.

Prerequisites

TypeScript

• Node.js 18 or later
• npm, yarn, or pnpm package manager

Check your Node.js version:

node --version

Rust

• Rust 1.70 or later
• Cargo package manager (included with Rust)

Install Rust if you haven't already:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Check your Rust version:

rustc --version

Install SDK

TypeScript

Install via your preferred package manager:

npm:

npm install @glin-ai/sdk

yarn:

yarn add @glin-ai/sdk

pnpm:

pnpm add @glin-ai/sdk

For TypeScript Projects

If you're using TypeScript, the SDK includes built-in type definitions. No additional @types packages needed!

tsconfig.json

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ESNext",
    "moduleResolution": "node",
    "lib": ["ES2020"],
    "types": ["node"]
  }
}

Rust

Add GLIN SDK to your Cargo.toml:

Cargo.toml

[dependencies]
glin-client = "0.1"
glin-contracts = "0.1"
glin-types = "0.1"
tokio = { version = "1", features = ["full"] }
anyhow = "1"

Or use cargo add:

cargo add glin-client glin-contracts glin-types
cargo add tokio --features full
cargo add anyhow

Version Compatibility

The GLIN Rust SDK requires:

• Rust 1.70+
• Tokio runtime for async operations
• Compatible with Substrate-based chains

Verify Installation

Let's verify the SDK is installed correctly:

TypeScript

Create a test file test.ts:

test.ts

import { GlinClient } from '@glin-ai/sdk';

console.log('✅ GLIN SDK installed successfully!');
console.log('Version:', require('@glin-ai/sdk/package.json').version);

Run it:

npx tsx test.ts
# or
node --loader ts-node/esm test.ts

Rust

Create a test file src/main.rs:

src/main.rs

use glin_client;

fn main() {
    println!("✅ GLIN SDK installed successfully!");
    println!("Version: {}", env!("CARGO_PKG_VERSION"));
}

Run it:

cargo run

Optional Dependencies

TypeScript

For browser-based applications:

npm install @polkadot/extension-dapp

For Next.js apps:

npm install @glin-ai/sdk next@15

Rust

For CLI development:

cargo add colored indicatif clap --features clap/derive

For indexer development:

cargo add sqlx --features runtime-tokio-rustls,postgres

Troubleshooting

Node.js: Module not found

If you see Cannot find module '@glin-ai/sdk':

1. Make sure you're in the correct directory
2. Run npm install again
3. Delete node_modules and package-lock.json, then reinstall

Rust: Compilation errors

If you see compilation errors:

1. Update Rust: rustup update
2. Make sure you're using Rust 1.70+: rustc --version
3. Clear cache: cargo clean && cargo build

Network Connection Issues

Make sure you can reach the GLIN testnet:

curl -I https://testnet.glin.ai
