Have you ever asked a GraphQL endpoint for one field and got back a wall of nulls? Do you rewrite the same query three times because you forgot a nested argument, then forget the variable declaration too? The GraphQL Query Generator turns a plain description of the data you want into a query, with the arguments placed correctly and the variables declared at the top.
GraphQL Query Generator takes a plain English brief naming the fields, filters and pagination you want, and returns the matching query, mutation or fragment, with the deeper selection sets and their arguments already assembled for you.
What is GraphQL Query Generator?
GraphQL asks you to say exactly what you want, which is a strength until the shape gets deep. GraphQL Query Generator takes the wanting in words and returns the asking in syntax. It handles the parts people get wrong most: nested selection sets, arguments on inner fields, variable declarations and fragments. It writes text, so nothing runs against your API until you paste the query in yourself.
Where it saves time
- Gets nested selection sets and inner arguments right first time
- Declares variables properly instead of inlining values
- Writes the matching mutation when you ask for one
Where you still do the work
- It has never seen your schema, so field names come from your brief
- Deprecated fields will not be flagged
- Pagination style has to be named, cursor or offset
How Does GraphQL Query Generator Work?
The panel here is shared with the REST tools, so the first move is to set API Style to GraphQL. Set Output to Spec / Schema when you want the query alongside the type definitions it assumes, or Endpoint Code when you want it wrapped in a client call. Set Auth to JWT or API Key if the request carries a header. What comes back is a single query block you paste into your playground, not a file you install.
Note Language / Framework only matters when you asked for Endpoint Code. For a bare query it changes nothing, so leave it blank and save yourself a decision.
Naming Fields, Arguments And Variables In Your Brief
The generator only knows the schema you describe. Say the query name, the fields you want back, the filters you will pass, and whether the result is a list or a single record. If your API uses connections and edges, say so, because a plain list query and a cursor paginated one look nothing alike.
| Left out of the brief | What tends to come back |
|---|---|
| No pagination style named | A plain list with no cursor or page arguments |
| No mention of nullability | Optional fields declared as required variables |
| No filter arguments given | A query that fetches everything and filters later |
One Brief Turned Into A Working Query
Say you need the fifty most recent pending orders with the total and the date, with status and page size passed as variables. Set API Style to GraphQL, set Output to Endpoint Code, leave the toggles alone and generate. The reply opens with something close to this.
query OrdersByStatus($status: String!, $first: Int) {
orders(status: $status, first: $first) { id total placedAt }
}Include Validation and Include Error Handling are on by default, so the wrapper around it checks the variables before sending and handles a failed response. Switch Include Docs on when you want the field notes as well.
Switching the AI model between attempts is free here, like the rest of EizTools, which asks for no account either. That helps when a query comes back oddly shaped and you want a second engine's attempt at the same brief. If the data behind your resolver still needs writing, the SQL Generator handles the plain English to SQL half of the job.
Frequently Asked Questions
Can it write mutations as well as queries?
Yes. Say what you are creating or updating, list the input fields, and name what you want returned. Mutations follow the same rule as queries: the more precise the brief, the closer the result.
Does it know my schema?
No. It has no connection to your API, so it works entirely from your description. Paste the relevant type definitions into the prompt box when you want field names matched exactly.
Why does a GraphQL tool have an API Style dropdown?
The panel is shared with the REST endpoint tools on EizTools. Set API Style to GraphQL and the rest of the options behave as you expect. Leaving it blank sometimes produces a REST style answer.
Will the generated query definitely run?
Only if the field names match your real schema. Run it in your playground first, fix any unknown field errors, and paste the corrections back into the prompt for a second pass.
GraphQL rewards precision and punishes a half remembered field path. Writing the brief in English and letting the syntax be generated keeps your attention on the data rather than the punctuation. Try the GraphQL Query Generator above on the query you were about to hand write, then run it against your own schema.
