Passing arguments to graphQL query
graphql, graphql-js
Solution
This really depends on how you want to design your API, there is no right or wrong to that answer and I'm not sure if there generally is a proper approach.
However, if you are certain about the scenario you're describing, then yes, `type`, `country` and `currency` should all be optional since you're leaving them out in some queries . If you didn't make these optional then your GraphQL server would throw errors if they're not passed in.
Another option could be that you wrap all of these arguments in a `filter` object with optional fields. Also, `type`, `currency` and `country` are probably better represented as enums than as strings :)
Problem
I am working on setting up a graphQL schema in node. The `/graphql` endpoint will typically be hit with argument(s) passed. For example, one API call may be looking for "checking" accounts: ``` query { accounts(type: "checking") { id type country currency } } ``` Another may be looking for all accounts in the "US": ``` query { accounts(country: "US") { id type country currency } } ``` ...and yet another may be looking for "savings" accounts in the "UK" denominated in "GBP": ``` query { accounts(type: "savings", country: "UK", currency: "GBP") { id type country currency } } ``` Is the proper approach defining this query as taking optional parameters for `type`, `country`, and `currency`?
