graphql-query-vars-cleaner

> Remove undefined variables from GraphQL queries.

Why?

Having a large number of undefined variables in a GraphQL can hurt performance on some backends.
For a query backing a table, you might have a filter and an order variable for each column.
Often it is easier to leave these variables as undefined, so instead graphql-query-vars-cleaner will filter out these undefined variables.

Installation

``bash
yarn add graphql-query-vars-cleaner
`

`bash
npm install graphql-query-vars-cleaner
`

> Note:
> GraphQL is a peer dependency. To run, also install graphql:
> Yarn: yarn add graphql
> NPM: npm install graphql

API

`js
import { getQuery } from "graphql-query-vars-cleaner";

const query =
query ($var1: Int, $var2: Int) {
field(where: $var1, and: $var2) {
x
y
}
};

const variables = {
var1: 1
};

console.log(getQuery(query, variables));

// Output:
// query ($var1: Int) { field (where: $var1) { x y } }

`

$3

type Variables = {
[name: string]: string | undefined;
}
