When using AOT in Angular, it is necessary to rewrite all functions and reducers to not utilize arrow functions:
An error occurred: Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function
Reducer using ES6 style:
export const config: ActionReducer<ConfigModel> = (state: ConfigModel = null, {type, payload}: action.ResponseActions) => {
switch (type) {
case configAction.LOAD_SUCCESS:
return ...;
default:
return state;
}
};
Rewritten to exported function style:
export function config(state: ConfigModel = null, {type, payload}: action.ResponseActions) {
switch (type) {
case configAction.LOAD_SUCCESS:
return ...;
default:
return state;
}
};
However, the type check is lost when using callable interfaces with a bare function signature.
ActionReducer<ConfigModel> is no longer specified. How do you specify that the config reducer implements the ActionReducer<ConfigModel>?
Is it possible to specify that the function implements a callable interface with a bare function?
ActionReducer (for completeness):
export interface ActionReducer<T, V extends Action = Action> {
(state: T | undefined, action: V): T;
}
