How to fight tons of unresolved variables warning in WebStorm?

I have a function that takes data from server:

function getData(data){
    console.log(data.someVar);
}

WebStorm says that someVar is an unresolved variable. How can I get rid of such warnings?

I see several options:

  • Suppress warnings in IDE settings;
  • Add a JSON source file with fields (details);
  • Use array-like syntax: data['some_unres_var'];

Also, WebStorm is offering me to create namespace for the "data" (add an annotation like /** @namespace data.some_unres_var*/), create such field, or rename it.

Solution

  • Use JSDoc:

    /**
 * @param {{some_unres_var:string}} data
 */
function getData(data){
    console.log(data.some_unres_var);
}
