Duplicate GraphQL Operation Names

duplicate-operation-name is a simple cli tool that makes it easy to check if there are any duplicate operation names in GraphQL projects that use static GraphQL queries.

It can be called on individual files, or recurisvely step through directories. It is compatible with .graphql, .ts, .tsx, .js, and .jsx files.

Installation

``shell
npm install -g duplicate-operation-name
`

Usage

The build tool binary is called duplicate-operation-name. Running it with no other arguments should give:

`
Usage: duplicate-operation-name [--graphql] [--js] [--ts]
`

input_path: can be a directory or file path

flags: at least one must be passed in

If any duplicate operation names are found, the script will exit with an error and print:
`
Error: Found duplicate operation names:
3 x myOperationName1
2 x myOperationName2
`

If no duplicate operation names are found, the script will exit without error and print:
`
No duplicates found!
`

If no queries are found, the script will exit without error and print:
`
No queries found.
`

It is also possible to analyze a directory containing .graphql, .ts., .tsx, .js and .jsx files:
