Cannot disable loopback explorer in production as specified in docs

[penguinpowernz]

The documentation says here and here that you can disable the API Explorer in production by making a file like this:

// server/component-config.json
{
  "loopback-component-explorer": {
    "mountPath": "/explorer"
  }
}

// server/component-config.production.json
{
  "loopback-component-explorer": false
}

And running the API with the NODE_ENV specified, like so:

NODE_ENV=production node .

However, when I do that I get this error:

$ NODE_ENV=production node .
/home/me/src/project/node_modules/loopback-boot/lib/config-loader.js:243
    throw new Error('Cannot apply ' + fileName + ': ' + err);
    ^

Error: Cannot apply /home/me/src/projec/server/component-config.production.json: Cannot merge values of incompatible types for the option `loopback-component-explorer`.

Has this process changed and the documentation not been updated? Changing false to an empty object doesn't disable the explorer either.

Here are my versions:

{
  "dependencies": {
    "compression": "^1.0.3",
    "cors": "^2.5.2",
    "loopback": "^2.22.0",
    "loopback-boot": "^2.6.5",
    "loopback-component-explorer": "^2.1.0",
    "loopback-connector-redis": "0.0.3",
    "loopback-datasource-juggler": "^2.39.0",
    "serve-favicon": "^2.0.1"
  },
  "devDependencies": {
    "jshint": "^2.5.6"
  }
}

Ran into the same issue. I was able to get it working by using:

{
  "loopback-component-explorer": {
    "mountPath": false
  }
}

I'm not sure whether the procedure changed or not. Maybe @bajtos has some insight here?

@crandmck Can we update the docs to reflect this?

This is a duplicate of strongloop/loopback-component-explorer#51 which has been fixed by strongloop/loopback-boot#168 and released as loopback-boot@2.17.0.

The patch mentioned above adds support for using null value to disable a component (false values is not supported). Here is the correct usage:

// server/component-config.production.json
{
  "loopback-component-explorer": null
}

@crandmck could you please update the docs?

[crandmck]

Updated both mentions in the doc noted above.
