D.A.T. CLI

Install D.A.T. with npm:

npm i -g @that-company/dat

Then sign in:

dat login

This npm package is a thin installer. During postinstall, it downloads the matching prebuilt dat binary from GitHub Releases, verifies it against SHA256SUMS, and exposes it as the dat command.

Alternative install:

curl -fsSL https://thatcompany.ai/install.sh | sh

Environment Overrides

• DAT_RELEASE_REPO: release repo, default that-company/dat-releases
• DAT_INSTALL_BASE: full release asset base URL
• DAT_CHANNEL: release path under /releases, default download/v<package version>
• DAT_SKIP_INSTALL=1: skip binary download during npm install

Release

The npm package version must match an already-published dat GitHub Release. The installer intentionally downloads from download/v<package version> instead of latest/download, so npm installs are reproducible and the package version has one meaning.

Release order is owned by the Release GitHub Actions workflow in this repo:

1. Build and publish the dat binary release to that-company/dat-releases.

2. Set this package version to the same X.Y.Z in the workflow workspace.

3. Run npm run verify:release.

4. Publish with npm Trusted Publishing/OIDC.

5. Verify npm view @that-company/dat version and a temp global install:

   npm install -g --prefix /tmp/dat-npm-check @that-company/dat@latest
   /tmp/dat-npm-check/bin/dat --version

The prepublishOnly hook runs the same release guard if someone uses npm publish --access public directly.
