Static Functions

Name	Description
`isConstruct`	Checks if `x` is a construct.
`isProject`	Test whether the given construct is a project.
`of`	Find the closest ancestor project for given construct.

`isConstruct`

import { GitHubActionTypeScriptProject } from 'projen-github-action-typescript'

GitHubActionTypeScriptProject.isConstruct(x: any)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

`x`^Required

Type: any

Any object.

`isProject`

import { GitHubActionTypeScriptProject } from 'projen-github-action-typescript'

public readonly runs: JavaScriptRuns | CompositeRuns | DockerRuns;

Type: JavaScriptRuns | CompositeRuns | DockerRuns

Specifies whether this is a JavaScript action, a composite action, or a Docker container action and how the action is executed.

`author`^Optional

public readonly author: string;

Type: string
Default: none

The name of the action's author.

`branding`^Optional

public readonly branding: Branding;

Type: Branding
Default: no branding

You can use a color and a Feather icon to create a badge to personalize and distinguish your action.

Badges are shown next to your action name in GitHub Marketplace.
