CLI Filtering

The task will be run on a workspace if all of the conditions are true.

• When any of the --only patterns match the workspace package.json#name; and
• When any of the --only-fs patterns match the workspace directory; and
• When all of the --ignore patterns do not match the workspace package.json#name; and
• When all of the --ignore-fs patterns do not match the workspace directory.

Patterns support any syntax available in micromatch:

workspaces-run --only-fs="**/path/to/dir/**"
workspaces-run --only="workspace-{one,two}"

Flags can be specified multiple times:

workspaces-run --only=<pattern> --only=<patern>

The flags --only-fs and --ignore-fs match against a relative path to the current working directory.

Library

import workspacesRun from "workspaces-run"

await workspacesRun({ cwd }, async (workspace, allWorkspaces) => {
  await doSomething(workspace)
})

opts.cwd (Required)

let cwd = process.cwd()

await workspacesRun({ cwd }, ...)

opts.parallel

await workspacesRun({ cwd, parallel: true }, ...)
await workspacesRun({ cwd, parallel: "physical-cores" }, ...)
await workspacesRun({ cwd, parallel: 3 }, ...)

opts.orderByDeps

await workspacesRun({ cwd, orderByDeps: true }, ...)
await workspacesRun({ cwd, orderByDeps: ["devDependencies"] }, ...)

opts.continueOnError

await workspacesRun({ cwd, continueOnError: true }, ...)

Library Filtering

The task will be run on a workspace if all of the conditions are true.

• When any of the only patterns match the workspace package.json#name; and
• When any of the onlyFs patterns match the workspace directory; and
• When all of the ignore patterns do not match the workspace package.json#name; and
• When all of the ignoreFs patterns do not match the workspace directory.

Patterns support any syntax available in micromatch:

await workspacesRun({
  cwd,
  only: ["workspace-{one,two}"],
  onlyFs: ["**/path/to/dir/**"],
}, ...)

The options onlyFs and ignoreFs match against a relative path to the cwd.
