IDE Support

IntelliJ

Melos integrates with IntelliJ via the generation of IntelliJ project module files (.iml files) during melos bootstrap.

Melos will create an IntelliJ project module for each package in your Melos workspace, and will create flutter and dart Run configurations for your main.darts and your package's test suite.

melos.yaml

Autocompletion and validation of melos.yaml can be enabled in IntelliJ by going to Settings > Languages & Frameworks > Schemas and DTDs > JSON Schema Mappings and adding the Melos schema:

• Schema url: https://raw.githubusercontent.com/blaugold/melos-code/main/melos.yaml.schema.json
• Schema version: JSON Schema version 7
• File: Select melos.yaml

VS Code

The Melos extension integrates Melos with VS Code.

melos.yaml

The extension provides validation and autocompletion of melos.yaml and allows you to run scripts through CodeLenses:

Melos scripts as tasks

Melos scripts are provided as VS Code tasks:

To configure a task that runs a Melos script, use task type melos:

// .vscode/tasks.json
{
  "version": "2.0.0",
  "tasks": [
    {
      "type": "melos",
      "script": "test",
      "label": "melos: test"
    }
  ]
}

Commands

The following commands are available in the command palette:

• Melos: Bootstrap to run melos bootstrap
• Melos: Clean to run melos clean
• Melos: Run script to select and run a Melos script
• Melos: Show package graph to show the package graph of the Melos workspace
