# 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 <input_path> [--graphql] [--js] [--ts]
```

**input_path**: can be a directory or file path

**flags**: at least one must be passed in

### Results

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.
```


### Analyzing Queries in GraphQL files (.graphql)

```shell
duplicate-operation-name queries.graphql --graphql
```

### Analyzing Queries in TypeScript files (.ts, .tsx)

```shell
duplicate-operation-name src/index.ts --ts
```

### Analyzing Queries in JavaScript files (.js, .jsx)

```shell
duplicate-operation-name src/index.js --js
```


### Analyzing Queries from Folders
It is also possible to analyze a directory containing `.graphql`, `.ts.`, `.tsx`, `.js` and `.jsx` files:

```shell
duplicate-operation-name src/ --graphql --ts --js
```
