SDK for Aptos Node API

Discord NPM Package Version NPM Package Downloads

Quickstart

The public SDK downloaded from npmjs is compatible with the Aptos devnet. To start building, run below command in your project directory:

pnpm add aptos

or use the browser bundle

<script src="https://unpkg.com/aptos@latest/dist/index.global.js" />

Then, the SDK can be accessed through window.aptosSDK.

Learn the basics of how to use the SDK by following this tutorial in the Aptos developer site.

Usage

For Javascript or Typescript usage, check out the ./examples folder with ready-made package.json files to get you going quickly!

If you are using the types in a commonjs module, like in a Node app, you just have to enable esModuleInterop and allowSyntheticDefaultImports in your tsconfig for types compatibility:

{
...
"compilerOptions": {
"allowSyntheticDefaultImports": true,
"esModuleInterop": true
...
}
}

Requirements

pnpm install

Generating API client

This SDK is composed of two parts, a core client generated from the OpenAPI spec of the API, and a set of wrappers that make it nicer to use, enable certain content types, etc.

To generate the core client from the spec, run:

pnpm generate-client

Working with devnet

See the quickstart above.

Working with local node

To develop in a local environment, you need to use the SDK from the main branch.

NOTE SDK from the main branch might not be compatible with the devnet.

Run a local node (run from the root of the repo):

cargo run -p aptos -- node run-local-testnet --with-faucet --faucet-port 8081 --force-restart --assume-yes

Run the SDK tests and make sure they pass. Go to the SDK directory, and setup an env to configure the URLs:

rm .env
echo 'APTOS_NODE_URL="http://127.0.0.1:8080/v1"' >> .env
echo 'APTOS_FAUCET_URL="http://127.0.0.1:8081"' >> .env

Run the tests:

pnpm test

If you see strange behavior regarding HTTP clients, try running the tests with --detectOpenHandles.

Package the SDK and start building:

pnpm build
pnpm pack
# In your project directory
pnpm add PATH_TO_LOCAL_SDK_PACKAGE

Semantic versioning

This project follows semver as closely as possible.

Release process

To release a new version of the SDK do the following.

  1. Regenerate the client:
pnpm generate-client
  1. Test, lint and format:
pnpm test
pnpm lint
pnpm fmt
  1. Bump the version in package.json according to semver.
  2. Add an entry in the CHANGELOG for the version. We adhere to Keep a Changelog.
  3. Once you're confident everything is correct, submit your PR. The CI will ensure that you have followed all the previous steps, specifically ensuring that the API, API spec, and SDK client are all compatible, that you've updated the changelog, that the tests pass, etc.
  4. Land the PR on main.
  5. Apply the changes to the devnet branch. CI will detect that the version has changed, build a new package, and upload it automatically to npmjs.
