Chimera-Framework

0.0.94 verified Sat Apr 25 auth: no javascript maintenance

Chimera-Framework is a language-agnostic framework for standalone and distributed computing, written in Node.js. Version 0.0.94 is the latest stable release, with low release cadence (last commit in 2018). It uses a component-based approach where components can be written in any language or even be binary executables. Orchestration is done via CHIML, a YAML superset. Key differentiators: language-agnostic components, CHIML-based workflow definition, supports both standalone and distributed modes.

Common errors

error Cannot find module 'chimera-framework' ↓

Warnings

gotcha Package uses ESM modules; require() will throw an error. ↓

fix Use import syntax or enable ESM in your project.

deprecated The CLI global command 'chimera' may not work with newer Node versions due to breaking changes in global package execution. ↓

fix Use npx chimera or run via import in a script.

gotcha Workflow execution is asynchronous; forgetting await may lead to undefined results. ↓

import { Chimera } from 'chimera-framework';
const chimera = new Chimera();
const workflow = `
ins: name
out: output
do:
  - |echo Hello, {name}! -> output
`;
const result = await chimera.run(workflow, { name: 'World' });
console.log(result); // "Hello, World!"
