Setup

Building nodejs bindings requires some extra setup.

For small or first-time contributions, we recommend the dev container method. Prefer to do it yourself? That's fine too!

Using a dev container environment

OpenDAL provides a pre-configured dev container that could be used in GitHub Codespaces, VSCode, JetBrains, JupyterLab. Please pick up your favourite runtime environment.

The fastest way is:

Bring your own toolbox

The nodejs binding requires Node.js@16+ to be built. We recommend using the latest TLS version for development.

OpenDAL provides a .node-version file that specifies the recommended node versions. You can use any compatible tool to install the correct node version, such as fnm.

Alternatively, you can manually install the LTS node by following these steps:

For Ubuntu and Debian:

> curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash - && sudo apt-get install -y nodejs
Copy

For RHEL, CentOS, CloudLinux, Amazon Linux or Fedora:

> curl -fsSL https://rpm.nodesource.com/setup_lts.x | sudo bash -
Copy

Afterward, you will need to enable corepack to ensure that pnpm has been set up correctly:

> sudo corepack enable
Copy

To verify that everything is working properly, run pnpm --version:

> pnpm --version
8.11.0
Copy

Using devbox

Launch Development Environment

devbox shell
Copy

Contains the following tools:

• node: 18
• pnpm: 8.14.0
• libiconv: fix nix ld missing issue

Running Scripts

• devbox run format
• devbox run test
• devbox run build
• devbox run dev

Build

# Install dependencies.
> pnpm install
# Build from source.
> pnpm build
# Build from source with debug info.
> pnpm build:debug
Copy

Test

We are using our own developed behavior testing framework. Taking 'service-memory' as an example, you can use the following command to run it.

> OPENDAL_TEST=memory pnpm test
