Publish, Versioning & Preview

Your app and the platform move on separate clocks

A metadata app is not part of the platform. It compiles to its own immutable artifact, carries its own version, and is released by you, when you decide. The platform — the runtime image, the kernel, the plugins — is released on the ObjectStack release train. Neither version implies the other, and neither has to wait for the other.

That independence is the point of the model, and it is also the question this page answers: if the app is a separate thing, how does it get into a running platform?

The compile half is always the same:

objectstack.config.ts -> os compile -> dist/objectstack.json

The delivery half has two shapes, and picking the wrong one is the expensive mistake. Both are described below, with the rule for choosing.

The one place the two clocks touch is the artifact's declared engines.protocol range: it states which platform majors the app can run on, and a runtime outside that range refuses the app rather than half-loading it. Everything else about the two versions is independent.

The two ways in

The rule for choosing

One question decides it:

Is this app the reason the runtime exists?

Yes — pin the artifact. The deployment defines the app, so the app belongs in the deployment's own inputs. No — install from the catalog. The runtime is a platform that receives apps, so apps arrive through a surface that stays open while it runs.

Three tie-breakers when both still look plausible:

1. Must "which bytes is this instance running?" have exactly one auditable answer? Pin the artifact. A #sha256= fragment makes the answer verifiable, and a mismatch stops the boot instead of quietly serving something else. A catalog install is a live mutation of a running platform — the right shape for an app store, the wrong shape for a reproducible deployment.
2. Must the app change without a restart, or must several apps share one runtime? Install from the catalog. The pinned artifact is resolved once, at boot; there is no in-place upgrade of it, by design.
3. Is there no catalog to reach (air-gapped)? Either still works, so choose on 1 and 2 rather than on connectivity: os package install ./dist/objectstack.json hands the compiled artifact over inline with no catalog round-trip, and OS_ARTIFACT_URL=file:///srv/app/objectstack.json pins a mounted file.

Using both at once

They are not exclusive, and the combination is well-defined:

• A pinned runtime still accepts installs. The install surface is mounted independently of how the runtime obtained its own app, so a runtime booted from OS_ARTIFACT_URL can still receive catalog installs — of other apps.

• Two sources naming the same app is a refusal, not a merge. An install whose manifest.id is already registered by the runtime's own boot is rejected with 409 MANIFEST_CONFLICT ("already defined by this runtime's local code") rather than overwriting it. Uninstall or unpin first; do not expect last-write-wins.

• Artifact sources have a fixed precedence, so a container that presets one variable cannot shadow a deliberate override:

  --artifact  >  OS_ARTIFACT_URL  >  OS_ARTIFACT_PATH  >  <cwd>/dist/objectstack.json

  OS_ARTIFACT_URL also outranks an objectstack.config.ts sitting in the working directory — setting it is an instruction to boot one specific artifact, not a hint.

1. Compile

os compile
# -> dist/objectstack.json

The artifact contains metadata, manifest requirements, and packaged function code. Deployment config stays outside the artifact: database URLs, secrets, runtime credentials, and environment identity are host inputs.

This one artifact feeds both delivery shapes — it is what os package publish uploads, and it is what an artifact host serves to OS_ARTIFACT_URL.

2. Publish a package version

# upload dist/objectstack.json as a new version in your org catalog
os package publish

# explicit artifact + install into an environment in one step
os package publish ./dist/objectstack.json --env env_prod --install

The CLI:

1. POST /api/v1/cloud/packages — ensure a sys_package row exists (id derived from artifact.manifest.id, or --manifest-id).
2. POST /api/v1/cloud/packages/:id/versions — snapshot dist/objectstack.json into sys_package_version.manifest_json (status published).
3. (optional) install the new version into --env.

Common flags:

In user mode the package is owned by your active organization; in service mode (bearer key) pass --org. See Packages for the package model.

Publishing changes nothing that is running. It puts a version in the catalog; step 3 is what moves an app.

3. Install a version

Two install targets, same catalog:

Into a Cloud environment — either at publish time with --env --install, or separately through the Cloud control plane / Marketplace. To "roll back," install the prior version; there is no revision-activate CLI command anymore.

Into a running runtime you operate — os package install calls that runtime's local install endpoint, which registers the app into the live kernel and caches the manifest on disk so the install survives a restart:

# catalog mode: the target runtime fetches the version from its own catalog
os package install com.acme.crm --version 1.2.0 --runtime https://app.example.com

# air-gapped mode: the artifact is read locally and sent inline, no catalog
os package install ./dist/objectstack.json

This authenticates against an account on the target runtime, not your cloud login. Uninstall removes the cached manifest; the kernel needs a restart to fully unload it, because app registration is additive.

For the full command reference — every flag, every subcommand — see the CLI reference.

4. Preview patterns

Use one of these shapes:

The third shape is worth using before a pinned rollout: it exercises the same boot path production will take, including the engines.protocol handshake and the boot-time schema-drift policy, against a local file.
