Mesh use cases are Api gateway only-no resolver support?

Hello Heena,

Thank you for your insightful question about the potential use cases of API Mesh.

API Mesh is an extensible reverse GraphQL proxy. To break this down:

• Reverse Proxy: It provides a single public endpoint that routes requests to multiple backend services.

• GraphQL Proxy: The public endpoint, generated after deploying the mesh, is a GraphQL endpoint.

• Extensible: You can enhance it by adding custom resolvers or hooks to modify how GraphQL operations are executed.

To answer your question, API Mesh functions as a gateway while also offering the flexibility to extend your sources with custom resolvers, enabling more advanced use cases.

We maintain a samples repository with various use cases and their corresponding mesh configurations. You can explore it here: Adobe Commerce Samples - API Mesh. We regularly update this repository with new use cases, and we'd love to have you contribute any additional ones you may have.

For a deeper understanding of the use cases and the inner workings of the mesh, I recommend checking out this video: Deep Dive into API Mesh.

Additionally, you can refer to the official documentation for comprehensive details: API Mesh Service Documentation.

I hope this clarifies things. Let me know if you have any further questions.

Hi @heenamadan ,

Use aio app init to scaffold the project.

Choose API Mesh extension during setup.

Ensure you place your mesh.json and customResolver.js correctly:

Your project should look like:

/src
   /api-mesh
       mesh.json
       customResolver.js
.env
.aio
package.json

Define the resolver in mesh.json like you already did:

{
"meshConfig": {
"sources": [
{
"name": "MagentoGraphQL",
"handler": {
"graphql": {
"endpoint": "https://domain.com/graphql",
"operationHeaders": {
"Content-Type": "application/json",
"store": "mystore"
}
}
}
}
],
"additionalResolvers": ["./customResolver.js"]
}
}

Install required dependencies:

npm install @graphql-mesh/cli @graphql-mesh/runtime @graphql-mesh/graphql

Add build command in your package.json (if needed):

"scripts": {
"mesh:dev": "graphql-mesh serve",
"mesh:build": "graphql-mesh build"
}

Run it locally to test (if needed):

npm run mesh:dev

Deployment with App Builder:
If you’re still getting issues on deployment:

• Make sure your .aio configuration includes your API Mesh extension.
• Use the aio app deploy command from the project root.
• Log into Adobe I/O with aio login if you haven’t.
• Check Adobe I/O Console for mesh-specific logs and failures.
