setting mimeTypes option falls with error

[webmasterslava]

setting mimeTypes option falls with error:

Error: Attempt to change mapping for "php" extension from "application/x-httpd-php" to "text/html". Pass `force=true` to allow this, otherwise remove "php" from the list of extensions for "text/html".

In webpack-dev-middleware/index.js file replace line

mime.define(options.mimeTypes);
by
mime.define(options.mimeTypes, true);

Isn't this something you could change in your php.ini/.htaccess? This would only supress the warning, but warnings are nice for different scenarios.

Could you provide a better elaboration of what you are trying to accomplish? Is it loading a php file? If so, then this should be sufficient as long as your proxy is defined correctly.

1. It's not a warning, it's error that doesn't allow to run node.js app that uses webpack-dev-middleware.
2. it's not related with php, php is just an example, I can use any other mime type that is already exists in the default list of mime types, and it will fall with error when I start node.js app.

Just hit this issue. I believe it happens when you have multiple webpack configs (e.g. client & server) so mime.define gets called twice with the same thing and that module throws the error.

"By default this method will throw an error if you try to map a type to an extension that is already assigned to another type. Passing true for the force argument will suppress this behavior (overriding any previous mapping)."

@gpoitch thanks for answer, can you send this to README?

@evilebottnawi Still need to figure out the best solution.

1. Update the code here with the force flag as @webmasterslava suggests mime.define(options.mimeTypes, true)
2. Expose an option to set the flag
3. Tell people to add their own code to manage only setting it once
4. PR to node-mime so it doesn't throw when defining a mime to the same thing it's already set to.

@gpoitch i think 2 solution is better, in some cases it is normal throw error, but we allow for other force define.

Fixed #349

@webmasterslava Answer here #346 (comment) and you can use force to redefine mime types
