Core engine for Jervis Installing.

Provides project detection, planning, execution, and link resolution for polyglot workflows — Node, PHP, Python, Ruby, Go, Rust, .NET, Java, Dart/Flutter, Elixir, and Makefile-based projects.

Exports

• detectProject — detects ecosystem(s), package manager, Node version
• planVerb — builds a step list for a given verb (up, install, deps, start, migrate, optimize, branch, doctor, pull)
• executePlan — runs the step list and emits structured log events
• createEmitter — creates a typed event emitter for log streaming
• loadManifest, saveManifest — read/write .jervis.yml
• linkProject, resolveLinkedProjects — manage linked project references

npm i jervis-installing-core

Usage

import {
  detectProject,
  planVerb,
  executePlan,
  createEmitter,
} from "jervis-installing-core";

const detection = await detectProject(process.cwd());
// detection.ecosystems → Set { 'node', 'php', ... }

const plan = planVerb(detection, "up");
const emitter = createEmitter();

emitter.on("log", (ev) => console.log(ev.msg));
await executePlan(plan, emitter);
