Package Exports

@solana/spl-token-swap

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@solana/spl-token-swap) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Token-swap JavaScript API

The Token-swap JavaScript library comprises:

A library to interact with the on-chain program
A test client that exercises the program
Scripts to facilitate building the program

Getting Started

First fetch the npm dependencies, including @solana/web3.js, by running:

$ npm install

Select a Network

The client connects to a local Solana cluster by default.

To enable on-chain program logs, set the RUST_LOG environment variable:

$ export RUST_LOG=solana_runtime::native_loader=trace,solana_runtime::system_instruction_processor=trace,solana_runtime::bank=debug,solana_bpf_loader=debug,solana_rbpf=debug

To start a local Solana cluster run:

$ npm run localnet:update
$ npm run localnet:up

Solana cluster logs are available with:

$ npm run localnet:logs

For more details on working with a local cluster, see the full instructions.

Build the on-chain program

$ npm run build:program

Run the test client

$ npm run start

Pointing to a public Solana cluster

Solana maintains three public clusters:

devnet - Development cluster with airdrops enabled
testnet - Tour De Sol test cluster without airdrops enabled
mainnet-beta - Main cluster

Use npm scripts to configure which cluster.

To point to devnet:

$ npm run cluster:devnet

To point back to the local cluster:

$ npm run cluster:localnet
