Methods ​

NameDescription
toString
Returns a string representation of this construct.
postSynthesize
Called after synthesis.
preSynthesize
Called before synthesis.
synthesize
Synthesizes files to the project output directory.
addPostBuildJob
Adds another job to the build workflow which is executed after the build job succeeded.
addPostBuildJobCommands
Run a sequence of commands as a job within the build workflow which is executed after the build job succeeded.
addPostBuildJobTask
Run a task as a job within the build workflow which is executed after the build job succeeded.
addPostBuildSteps
Adds steps that are executed after the build.
toString ​
public toString(): string

Returns a string representation of this construct.

postSynthesize ​
public postSynthesize(): void

Called after synthesis.

Order is not guaranteed.

preSynthesize ​
public preSynthesize(): void

Called before synthesis.

synthesize ​
public synthesize(): void

Synthesizes files to the project output directory.

addPostBuildJob ​
public addPostBuildJob(id: string, job: Job): void

Adds another job to the build workflow which is executed after the build job succeeded.

Jobs are executed only if the build did NOT self mutate. If the build self-mutate, the branch will either be updated or the build will fail (in forks), so there is no point in executing the post-build job.

idRequired ​
  • Type: string

The id of the new job.

jobRequired ​
  • Type: projen.github.workflows.Job

The job specification.

addPostBuildJobCommands ​
public addPostBuildJobCommands(id: string, commands: string[], options?: AddPostBuildJobCommandsOptions): void

Run a sequence of commands as a job within the build workflow which is executed after the build job succeeded.

Jobs are executed only if the build did NOT self mutate. If the build self-mutate, the branch will either be updated or the build will fail (in forks), so there is no point in executing the post-build job.

idRequired ​
  • Type: string
commandsRequired ​
  • Type: string[]
optionsOptional ​

Specify tools and other options.

addPostBuildJobTask ​
public addPostBuildJobTask(task: Task, options?: AddPostBuildJobTaskOptions): void

Run a task as a job within the build workflow which is executed after the build job succeeded.

The job will have access to build artifacts and will install project dependencies in order to be able to run any commands used in the tasks.

Jobs are executed only if the build did NOT self mutate. If the build self-mutate, the branch will either be updated or the build will fail (in forks), so there is no point in executing the post-build job.

taskRequired ​
  • Type: projen.Task
optionsOptional ​

Specify tools and other options.

addPostBuildSteps ​
public addPostBuildSteps(steps: ...JobStep[]): void

Adds steps that are executed after the build.

stepsRequired ​
  • Type: ...projen.github.workflows.JobStep[]

The job steps.

Static Functions ​

NameDescription
isConstruct
Checks if x is a construct.
isComponent
Test whether the given construct is a component.
isConstruct ​
import { build } from 'projen'

build.BuildWorkflow.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.

xRequired ​
  • Type: any

Any object.

isComponent ​
import { build } from 'projen'

build.BuildWorkflow.isComponent(x: any)

Test whether the given construct is a component.
