brGuirra/mf-context

Collect the following information step by step from $ARGUMENTS (defaults to the current working directory if empty), then output the aggregated MFContext.

1. Basic Info

Read {projectRoot}/package.json and extract:

• name: project name
• Merge dependencies + devDependencies into a full dependency map

Detect the package manager (check files in order):

• pnpm-lock.yaml → pnpm
• yarn.lock → yarn
• package-lock.json → npm

2. Bundler & MF Config

Find config files in the following priority order (.ts / .mts take precedence over .js / .mjs / .cjs):

| Priority | Filename | |---|---| | 1 | module-federation.config.{ts,mts,js,mjs,cjs} | | 2 | rsbuild.config.{ts,mts,js,mjs,cjs} | | 3 | rspack.config.{ts,mts,js,mjs,cjs} | | 4 | modern.config.{ts,mts,js,mjs,cjs} | | 5 | next.config.{ts,mts,js,mjs,cjs} | | 6 | webpack.config.{ts,js} |

Read the first matched file and extract the remotes, exposes, and shared fields. Determine the bundler from the filename (rspack / rsbuild / webpack).

3. Determine MF Role

| Condition | Role | |---|---| | Has remotes and exposes | host+remote | | Only remotes | host | | Only exposes | remote | | Neither | unknown |

4. Recent Error Event (optional)

Check if .mf/diagnostics/latest.json exists; if so, read its contents.

5. Build Artifacts (optional)

Check if dist/mf-manifest.json and dist/mf-stats.json exist; if so, read them.

Aggregate the above information and output the MFContext summary in the following structure:

project:
  name, packageManager, mfRole

bundler:
  name, configFile

mfConfig:
  remotes, exposes, shared

dependencies:
  (list installed packages related to MF and their versions)

latestErrorEvent: (if present)
buildArtifacts:   (if present)
