Bug: Generate projects, even if project don't have any components. Improved UIDL validations for root and component UIDL

[JayaKrishnaNamburu]

#487

We use ComponentUIDL to carry out all operations needs for generating components. But we use the ComponentUIDL for maintaining root in ProjectUIDL. But there are slight changes needed in order to validate.

Root Component UIDL

• name
• node
• propDefinitions
• stateDefinitions
• importDefinitions
• peerDefinitions
• styleSetDefinitions
• outputOptions
• seo

Component UIDL

• name
• node
• propDefinitions
• stateDefinitions
• importDefinitions
• outputOptions
• seo

In root the stateDefinitions are not optional but in component they are optional. Since in root we need them to construct routes. So, ti handle this unique validations no we have two diff validators for components. componentUIDLValidator and rootComponentUIDLValidator.

By default the @teleporthq/teleport-component-generator uses componentUIDLValidator unless a flag is explicitly passed to use rootComponentValidator.

Like this

const result = await generator.generateProject(uidl, { isRootComponent: true})

When this flag is passed, it starts to validate the component using rootComponentValidator. This is automatically handled by our project generators while validating a project.

• A small bug-fix to generate projects even when components are not used and defined in the projectUIDL
