@island.is/pipes-core

Pipes is dev-friendly, testable pipelines library for local & CI/CD platforms, written in Typescript.

⚠️Disclaimer⚠️: This software is currently in development and is not considered production-ready. It more than likely contains bugs, incomplete features, or other discrepancies. Use at your own risk.

It is strongly advised to NOT USE this software in a production environment or for critical applications until it has been thoroughly tested and deemed stable.

Here are the core components of Pipes:

• A highly modular runner, with, states, configuration, locking mechanism and storage, using Dagger to run the code anywhere!

• An extended version of Zod, which is a schema validation library. Our extension enriches Zod's capabilities, tailoring it to the specific needs of our CI/CD processes.

• All functionalities and tools highly integrated to deliver a seamless deployment experience.

PipeCoreRunner

This class is responsible for managing the lifecycle and execution of multiple "PipesCoreClass" (context) instances, acting as the main runner for your pipe-based application.

Normally developers should use createPipe to define it.

Methods

Method Signature	Description	Arguments	Return Type
addContext(value: PipesCoreClass): () => void	Adds a new context to the internal context set.	value (PipesCoreClass): The context object to add.	A function that removes the added context when called.
removeContext(value: PipesCoreClass): void	Removes a context from the internal context set.	value (PipesCoreClass): The context object to remove.	void
async run(): Promise<void>	Initiates the execution of all stored contexts. Asynchronously waits for all contexts to complete.	None	A Promise that resolves when all contexts are done executing.

createPipe(fn: ({ z, createPipesCore }: CreatePipeProps) => Promise<PipeBase[]> | PipeBase[]): Promise<void>

Description

Creates and runs a pipe using the provided function. The function passed to createPipe should return an array of PipeBase objects, which will be added to the internal context set for execution.

Arguments

• fn: A function that takes an object with properties:

  • z
  • createPipesCore - create new context
  • createConfig - creates new Config for a module
  • createContext - creates new Context for a module
  • createModule - creates new Module
  • contextHasModule - type-guard for if context has module
  • configHasModule - type-guard for if context config has module

  The function should return a Promise that resolves to an array of PipeBase objects, or directly return an array of PipeBase objects.

Returns

A Promise that resolves when all contexts (pipes) returned by the fn function are done executing.

Example Usage

await createPipe(async ({ z, createPipesCore }) => {
  // Your logic here
  return [
    /* array of PipeBase objects */
  ];
});
