Cdklabs Projen Project Types

This repository stores custom project types extended from projen with cdklabs defaults baked in. This is meant to serve as a hook for continuous management of all repos we own. With cdklabs projen types, we can add new configuration as they come up and have it propagate to all repositories using the type.

CdklabsConstructLibrary

This type extends projen's awscdk.AwsConstructLibrary project type and should be used in place of that type.

Usage

From the command line:

npx projen new --from cdklabs-projen-project-types cdklabs-construct-lib

From inside cdk-ops:

this.cdklabs.addPreApprovedRepo({
  repo: 'cdk-new-lib',
  owner: 'conroyka@amazon.com',
  createWith: {
    projectType: ProjectType.CDKLABS_MANAGED_CONSTRUCT_LIB,
  },
});

Features

• cdklabsPublishingDefaults

By default, this is turned on. cdklabsPublishingDefaults provides publishing defaults based off of the project's name. Specifically, the defaults look like this:

return {
  publishToPypi: {
    distName: npmPackageName,
    module: changeDelimiter(npmPackageName, '_'),
  },
  publishToMaven: {
    javaPackage: `io.github.cdklabs.${changeDelimiter(npmPackageName, '.')}`,
    mavenGroupId: 'io.github.cdklabs',
    mavenArtifactId: npmPackageName,
    mavenEndpoint: 'https://s01.oss.sonatype.org',
  },
  publishToNuget: {
    dotNetNamespace: `Cdklabs${upperCaseName(npmPackageName)}`,
    packageId: `Cdklabs${upperCaseName(npmPackageName)}`,
  },
  publishToGo: {
    moduleName: `${npmPackageName}-go`,
  },
};

Additionally, we also require that we publish to all jsii language targets (including go) when we specify a library as stable.

• private

By default, a project is created as private. Turning this off simply means setting private: false. A project being private means it gets certain properties set as default that are true for private projects. Today, that means setting private: true in package.json, removing .mergify.yml from the project, and removing .npmignore.

• releasableCommits

By default this project type releases ReleasableCommits.featuresAndFixes, to not release a new version every day on a package that only sees devDependency updates. You may want to override this if you need something more specific.

CdklabsTypeScriptProject

This type extends projen's typescript.TypeScriptProject project type and should be used in place of that type.

Usage

npx projen new --from cdklabs-projen-project-types cdklabs-ts-proj

From inside cdk-ops:

this.cdklabs.addPreApprovedRepo({
  repo: 'cdk-new-lib',
  owner: 'conroyka@amazon.com',
  createWith: {
    projectType: ProjectType.CDKLABS_MANAGED_TS_PROJECT,
  },
});

Features

• private

By default, a project is created as private. Turning this off simply means setting private: false. A project being private means it gets certain properties set as default that are true for private projects. Today, that means setting private: true in package.json, removing .mergify.yml from the project, and removing .npmignore.

CdklabsMonorepo

A TypeScript monorepo using Yarn Workspaces. Individual workspaces can be added with yarn.TypeScriptWorkspace which extends projen's typescript.TypeScriptProject.

Usage

npx projen new --from cdklabs-projen-project-types cdklabs-yarn-monorepo

Features

const project = new yarn.CdkLabsMonorepo({
  defaultReleaseBranch: "main",
  devDeps: ["cdklabs-projen-project-types"],
  name: "monorepo",
});

• Workspace commands: projen build|compile|package|test|upgrade
  Will run the specific command in all workspaces and the root if applicable.

• Workspace run: projen run <command>
  Executes the given command in all workspaces

• Automatic dependency installation
  The monorepo will know if a dependency has been added for a workspace and run yarn install as part of projen

• projen at any level
  The default projen command can be run in any workspace and will execute the monorepo synth command.

• Release
  This feature is not supported at this time. Any release functionality must be implemented.

• vscodeWorkspace: boolean
  You can specify if a VSCode Workspace file should be created for the monorepo.

Workspaces

new yarn.TypeScriptWorkspace({
  parent: project,
  name: 'workspace'
})

• parent: yarn.Monorepo
  Workspaces (aka subprojects) must be added using the parent option.

• workspaceScope: string
  The location the workspace is placed at. Defaults to ./packages

• excludeDepsFromUpgrade: Array<string>
  List any dependencies that should not be updated in the workspace.
