monop

build status npm version

Monop is a npm-scripts hook for lazy development of dizzying monorepo applications.

Installation

$ npm install -g monop

Usage

Monop is CLI tool for monorepo applications like below.

some-project/
├── monop-workspace.json
├── package.json
└── packages
    ├── pkg-1
    │   ├── index.js
    │   └── package.json
    ├── pkg-2
    │   ├── index.js
    │   └── package.json
    └── pkg-3
        ├── index.js
        └── package.json

This project has package.jon in the project root, and workspaces under packages/ directory. Each workspace has package.json too.

The project needs monop-workspace.json, Monop configuration file, to be managed by Monop. Monop sees the directory where it is as the project root.

Syntax of monop-workspace.json

Example:

{
  "workspaces": ["packages/*/package.json"]
}

.workspaces

Set array of glob pattern strings. Monop search workspaces with the patterns. The pattern must be ends with package.json. Monop will ignore node_modules by default.

.commonLocalDependencies

Set array of workspacce package names. They will be common localDependencies.

Monop commands

Monop provides monop command.

monop link

Creates symbolic links of all locaDependencies under node_modules in each workspace. This enables each workspace to use others.

$ monop link [options] <workspace_query>

Example:

$ monop link all
[monop] Create symlinks in @project01/pkg-2
[monop] Symlink: packages/pkg-2 -> packages/pkg-2/node_modules/@project01/pkg-1

[monop] Create symlinks in @project01/pkg-3
[monop] Symlink: packages/pkg-3 -> packages/pkg-3/node_modules/@project01/pkg-2

In this case, @project01/pkg-1 depends on @project01/pkg-2, and @project01/pkg-2 depends on @project01/pkg-3.

monop list

Shows all workspaces.

monop exec

Executes a command in workspaces.

$ monop exec [options] <workspace_query> <command...>

Example:

$ monop exec pkg-3 npm install

npm install will be run in packages/pkg-3. You can run this command in everywhere directory under the project root.

Workspace Query

Workspace query string can be:

  • Workspace name (the pachage name package.json)
  • Workspace short name (You can see by monop list)
  • Workspace directory relative path (For example, .)
  • You can spacify all workspaces with all

You can use the option --chain. The word "chain" means all local dependencies of the workspace searched recursively. With the option --chain, the command run in all "chain" workspaces.

Examples:

# Exec "npm run prepare" in all workspaces
$ monop exec all npm run prepare
# Exec "npm install" in all chain workspaces of pkg-3
$ monop exec --chain pkg-3 npm install
# Exec "npm install" in all chain workspaces of current directory workspace
$ monop exec --chain . npm install

About "localDependencies"

The command monop exec --chain requires custom field .monop.localDependencies in package.json in each workspace to specify local package dependencies.

Example:

{
  "monop": {
    "localDependencies": [
      "@project01/pkg-2"
    ]
  }
}
