Marko Router Component

After installing marko-router copy the folder ./node_modules/marko-router/components/marko-router into your Marko components folder. This component will ease the interaction with marko-router and it's fully customizable for your needs. Due to Marko/Lasso limitation I was unable to make marko-router an actual Marko component with all the features this alternative approach introduced.

Marko Router Config

// views/components/marko-router/marko-router-config.json

{
  // Root State
  "myRootState": {
    // Base path for this root state (e.g. handle all the requests at .../myRootState/*)
    "_base": "/myRootState",
    // Default state (default redirects for '/')
    "_default": "myPageStart",
    // State for myPageStart
    "myPageStart": {
      // Route segment for this state
      "path": "/myPageStart",
      // Component Details
      "component": {
        // Component Key
        "key": "myRootState-route-myPageStart",
        // Static Component Params
        "params": {}
      }
    },
    // State for myPageNext
    "myPageNext": {
      // Route segment for this state
      "path": "/myPageNext",
      // Component Details
      "component": {
        // Component Key
        "key": "myRootState-route-myPageNext",
        // Static Component Params
        "params": {}
      }
    },
    // State for myPageNext with url params
    "myPageNextWithParam": {
      // Route segment for this state
      "path": "/myPageNext/:p",
      // Component Details
      "component": {
        // Override state
        "state": "myPageNext",
        // Component Key
        "key": "myRootState-route-myPageNext",
        // Static Component Params
        "params": {}
      }
    },
    ...
    // Redirect
    "/myPageLast": "/myPageStart",
    // State to handle Not Found
    "notfound": {
      // Route segment for this state
      "path": "*",
      // Component Details
      "component": {
        // Component Key
        "key": "myRootState-route-notfound",
        // Static Component Params
        "params": {}
      }
    }
  }
}

Essentially the marko-router-config.json has the following constraints:

• Root states are always first level properties
• Root state must always define _base, _default
• Root state _base must be a url segment just starting with /
• Root state _default must be a state correctly defined within the root state
• States are always second level properties
• States cannot start with _
• States must always define path, component.key, component.params
• State path must be defined accordingly PageJS documentation
• State component.key must be exactly the key of the state component
• State component.param must be an object and if not defined must be an empty object {}
