Manifest Backend YAML Best Practices for Cursor AI App Development
Master lightweight Manifest backend creation in Cursor AI with these optimized rules: setup scripts, YAML schema compliance, entity limits, and demo-focused structures for quick app prototypes.
1. **Initialize Project Dependencies**: Begin by installing the 'manifest' npm package to enable backend generation capabilities.
2. **Configure Package Scripts**: Update package.json with custom scripts: 'manifest' for running the watch process via 'node node_modules/manifest/scripts/watch/watch.js', and 'manifest:seed' for seeding data using 'node node_modules/manifest/dist/manifest/src/seed/scripts/seed.js'.
3. **Generate Backend Configuration File**: Create a 'manifest/backend.yml' file and populate it with the schema-defined backend structure.
4. **Enhance VSCode Support**: Recommend the 'redhat.vscode-yaml' extension in '.vscode/extensions.json' and apply YAML schema validation in '.vscode/settings.json' by associating '**/manifest/**.yml' files with the Manifest schema.
5. **Adhere to YAML Schema Strictly**: Ensure the backend.yml file conforms precisely to the official Manifest schema, starting with a concise app name.
6. **Limit Scope for Demos**: Restrict to 2-3 entities max, each with no more than 4 properties, emphasizing variety in property types like date, number, richText, or image.
7. **Minimize Validations**: Incorporate validation rules sparingly, only 1-2 times across the file.
8. **Entity Naming Conventions**: Avoid 'admin' names, skip authenticable entities, prefix each entity with a relevant emoji (but omit in relationship refs), and insert line breaks before each entity block.
9. **Streamline Relationships**: Define relationships directly after properties using short YAML form like 'belongsTo: - Owner', without repeating entity names or using special characters.
10. **Omit Advanced Features**: Exclude middlewares, endpoints, hooks, seedCount, mainProp, and relationships on solo entities.
11. **Format Properties Concisely**: Use YAML shorthand for objects, e.g., '{ name: issueDate, type: date }' with proper spacing.
12. **Handle Choice Properties**: For 'choice' types, specify options via 'options.values' array, e.g., '{ name: type, type: choice, options: { values: ["Fire", "Water", "Grass"] } }'.
13. **Implement Basic Policies**: Apply simple public policies like 'read' for all, or add 'create' for open submissions such as forms or comments.
14. **Focus on Demo Readiness**: Design light structures showcasing property diversity without full data models, ideal for prototypes.Comments
