How to use https://stashdb.org/graphql​

Introduction to StashDB GraphQL

StashDB’s GraphQL API is a powerful tool for accessing and interacting with data stored in StashDB. GraphQL, a query language for APIs, enables developers to request specific data and shape the responses according to their needs, ensuring efficiency and flexibility.

This guide provides an in-depth tutorial on how to use https://stashdb.org/graphql effectively, from setting up your environment to executing complex queries.

What is StashDB GraphQL?

StashDB’s GraphQL API allows users to:

• Fetch specific data from the database.
• Perform complex data queries with minimal overhead.
• Define the structure of the returned data.

By leveraging GraphQL, users can reduce the need for multiple API calls, improving performance and simplifying development.

Setting Up Your Environment

Prerequisites

Before you begin using the API, ensure you have:

1. Basic knowledge of GraphQL.
2. A StashDB account with API access.
3. Tools such as:
   • GraphQL Playground or Postman.
   • A programming environment (e.g., Node.js).

Accessing the GraphQL Endpoint

The GraphQL endpoint for StashDB is:

https://stashdb.org/graphql

You’ll need an API token to authenticate requests. Obtain the token by logging into your StashDB account and navigating to the API section.

Understanding the GraphQL Query Structure

GraphQL queries consist of:

• Queries: For retrieving data.
• Mutations: For modifying data.
• Fragments: For reusing query parts.

Example Query

Here’s a basic query to fetch an item by ID:

query GetItem($id: ID!) {
  item(id: $id) {
    id
    name
    description
  }
}

Variables

Variables enable dynamic queries. For the above query, you can pass the variable:

{
  "id": "12345"
}

Performing Your First Query

1. Open GraphQL Playground or Postman.
2. Set the Endpoint: Use https://stashdb.org/graphql.
3. Add Headers: Include your API token.

Example:

{
  "Authorization": "Bearer YOUR_API_TOKEN"
}

4. Run a Query:

For example, to fetch all items:

query GetAllItems {
  items {
    id
    name
    description
  }
}

Common Queries and Use Cases

Fetch All Items

query GetAllItems {
  items {
    id
    name
    description
  }
}

Search for Items by Keyword

query SearchItems($keyword: String!) {
  searchItems(keyword: $keyword) {
    id
    name
    description
  }
}

Variables:

{
  "keyword": "example"
}

Add a New Item (Mutation)

mutation AddItem($name: String!, $description: String!) {
  addItem(input: { name: $name, description: $description }) {
    id
    name
  }
}

Variables:

{
  "name": "New Item",
  "description": "A description of the new item."
}

Best Practices for Using StashDB GraphQL

1. Optimize Queries: Request only the fields you need.
2. Use Fragments: Simplify complex queries by reusing fragments.
3. Paginate Results: Use pagination to handle large datasets.

Example:

query PaginatedItems($limit: Int!, $offset: Int!) {
  items(limit: $limit, offset: $offset) {
    id
    name
  }
}

Variables:

{
  "limit": 10,
  "offset": 0
}

4. Secure Your Token: Never expose your API token in public repositories.
