## Summary This PR is part of the Kibana Sustainable Architecture effort. The goal is to start categorising Kibana packages into _generic platform_ (`group: "platform"`) vs _solution-specific_. ``` group?: 'search' | 'security' | 'observability' | 'platform' visibility?: 'private' | 'shared' ``` Uncategorised modules are considered to be `group: 'common', visibility: 'shared'` by default. We want to prevent code from solution A to depend on code from solution B. Thus, the rules are pretty simple: * Modules can only depend on: * Modules in the same group * OR modules with 'shared' visibility * Modules in `'observability', 'security', 'search'` groups are mandatorily `visibility: "private"`. Long term, the goal is to re-organise packages into dedicated folders, e.g.: ``` x-pack/platform/plugins/private x-pack/observability/packages ``` For this first wave, we have categorised packages that seem "straightforward": * Any packages that have: * at least one dependant module * all dependants belong to the same group * Categorise all Core packages: * `@kbn/core-...-internal` => _platform/private_ * everything else => _platform/shared_ * Categorise as _platform/shared_ those packages that: * Have at least one dependant in the _platform_ group. * Don't have any `devOnly: true` dependants. ### What we ask from you, as CODEOWNERS of the _package manifests_, is that you confirm that the categorisation is correct: * `group: "platform", visibility: "private"` if it's a package that should only be used from platform code, not from any solution code. It will be loaded systematically in all serverless flavors, but solution plugins and packages won't be able to `import` from it. * `group: "platform", visibility: "shared"` if it's a package that can be consumed by both platform and solutions code. It will be loaded systematically in all serverless flavors, and anybody can import / use code from it. * `group: "observability" | "security" | "search", visibility: "private"` if it's a package that is intented to be used exclusively from a given solution. It won't be accessible nor loaded from other solutions nor platform code.

--- id: kibDevDocsOpsRepoSourceClassifier slug: /kibana-dev-docs/ops/repo-source-classifier title: "@kbn/repo-source-classifier" description: 'The tool which classifies source files into categories' date: 2022-07-25 tags: ['kibana', 'dev', 'contributor', 'operations', 'packages', 'scripts'] --- This package exposes a class which can be used to efficiently classify all of the files in the repository into one of the following groups: - `server package`: plugin code in the root `server/` directory, eventually this will include packages of type `server-plugin` or `server-shared` - `browser package`: plugin code in the root `public/` directory (and a few others in specific plugins), eventually this will include packages of type `browser-plugin` or `browser-shared` - `common packages`: includes any existing package, plugin code in root `common/` directories, (and a few others in specific plugins), Eventually this will include `common-shared` packages - `tests or mocks`: code that is loaded by jest/storybook, and mocks/helpers intended for use by that code. These files usually live along side package code but will have a separate dependency tree and are pieces of code which should never end up in the product. - `static`: static files, currently any .json file or things loaded via `raw-loader` in browser code - `tooling`: scripts, config files for tools like eslint, webpack, etc. - `non-package`: code that lives outside of packages/plugins or doesn't fit into other more specific categories. Once the package project is complete this category should be limited to just `@kbn/pm` This is a map of types to the types they are allowed to import: - `non-package`: `non-package`, `server package`, `browser package`, `common package` or `static` - `server package`: `common package`, `server package`, or `static` - `browser package`: `common package`, `browser package`, or `static` - `common package`: `common package` or`static` - `static`: static files are not allowed to have dependencies - `tests or mocks`: anything - `tooling`: anything The `RepoSourceClassifier` class implements several caches to make these lookups as efficient as possible in ESLint when all imports across the entire repository are validated. This cache lasts for the lifetime of the class and to invalidate the cache the object should just be discarded and a new instance created. A CLI is provided for inspecting the results of the classifier, check out `node scripts/classify_source --help` for more information about usage.
