Eric Hare 8a1a1f367b feat(lfx): installed-package + seed-directory discovery for production install (LE-1022)
Adds the read-only production install path for Modes A, B, and C of the
Bundle Separation iteration. Manifest-shipping pip-installed
distributions and seed-directory subdirectories are discovered at server
startup and registered as Extensions at @official.

* discovery.py: walks importlib.metadata.distributions() + the
  $LANGFLOW_SEED_DIR / /opt/langflow/bundles seed root; produces
  DiscoveredExtension records and typed errors for malformed manifests
  / configured-but-missing seed dirs.
* registry.py: ExtensionRegistry service with the immutability
  invariant for installed and seed entries. Mutation verbs (uninstall,
  disable, enable, install, update_entry) all raise
  ExtensionImmutableError carrying the typed
  installed-extension-immutable / seed-directory-immutable code so the
  invariant is testable today; the CLI uninstall surface ships in B4.
* lfx extension list: read-only inspector with text and JSON output
  for operators inspecting Mode B/C images.
* Errors: four new typed codes
  (installed-extension-immutable, seed-directory-immutable,
  seed-directory-not-found, duplicate-extension-id) plus snapshot
  coverage in tests/unit/extension/test_errors.py.
* Tests: 165 extension tests pass, including the LE-1022 acceptance
  cases -- three pip-installed wheels visible at @official, three seed
  bundles visible at @official, and the parametrized service-layer
  immutability check across every mutation verb.
* Docs: docs/Deployment/deployment-extensions-production.mdx covers
  the Dockerfile template, k8s deployment notes, the bundle packaging
  convention (extension.json shipped via package-data), and
  troubleshooting for the typed error codes.

Website

This website is built using Docusaurus 3, a modern static website generator.

Installation

$ npm install

Local Development

$ npm run start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

$ npm run build

This command generates static content into the build directory and can be served using any static contents hosting service, including npm run serve.

Import code snippets from the repo with a line range

To pull a slice of a file into the docs, source the content with raw-loader and present the code with the CodeSnippet component. For a working example, see the Components overview.

import CodeSnippet from "@site/src/components/CodeSnippet";
import customComponent from "!!raw-loader!@langflow/src/lfx/src/lfx/custom/custom_component/custom_component.py";

<CodeSnippet
  source={customComponent}
  startLine={41}
  endLine={74}
  language="python"
  title="CustomComponent metadata (from codebase)"
  showLineNumbers
/>

Docusaurus Versioning

The versioning configuration is found in docusaurus.config.js.

Versioning example for release version 1.9.x on top of 1.8.x:

  1. Before release, the docs in the active release branch should already be set to 1.8.x, the current version.
  2. When ready to release 1.9.x, create a branch and run npm run docs:version -- 1.9.0 to snapshot the current docs.
  3. After creating a new version, update docusaurus.config.js to include the 1.9.0 release:
docs: {
  lastVersion: '1.9.0',
  versions: {
    '1.9.0': {
      label: '1.9.x',
      path: '1.9.0',
    },
    '1.8.0': {
      label: '1.8.x',
      path: '1.8.0',
    },
  },
},
  1. Test the deployment locally:
npm run build
npm run serve
  1. Create a pull request to main, and merge to create your new release.
  2. To create version 2.0.x, repeat the process: update the active release branch docs to 2.0.x when you begin working on it, then when ready to release, run npm run docs:version -- 2.0.0, update docusaurus.config.js with labels using .x notation, and merge to main.
  • lastVersion = the most recent released version (shown as "latest" in the UI).

See the Docusaurus docs for more info.

Disable versioning

  1. Remove the versions configuration from docusaurus.config.js.
  2. Delete the docs/versioned_docs/ and docs/versioned_sidebars/ directories.
  3. Delete docs/versions.json.
