Project Description


Apollo Tooling is a set of tools and libraries that are built on top of Apollo GraphQL. It includes the following components:

    1. Apollo Boost: A zero-configuration, opinionated GraphQL client that includes the most commonly used features of Apollo Client.
    2. Apollo CLI: A command-line tool for generating GraphQL code and for working with GraphQL servers.
    3. Apollo Studio: A cloud-based platform for managing and optimizing GraphQL APIs.


Troubleshooting Apollo GraphQL – Apollo Tooling with the Lightrun Developer Observability Platform


Getting a sense of what’s actually happening inside a live application is a frustrating experience, one that relies mostly on querying and observing whatever logs were written during development.
Lightrun is a Developer Observability Platform, allowing developers to add telemetry to live applications in real-time, on-demand, and right from the IDE.
  • Instantly add logs to, set metrics in, and take snapshots of live applications
  • Insights delivered straight to your IDE or CLI
  • Works where you do: dev, QA, staging, CI/CD, and production

The most common issues for Apollo GraphQL – Apollo Tooling are:


Codegen collaboration with Apollo Codegen and GraphQL Code Generator


To further optimize user experience, developers can explore the Apollo Option of –passthroughCustomScalars. Adding a scalar key to  codegen.yml file will enable users to capitalize on its full potential and enhance their project created with Codegen!

VS Code extension self signed certificate error


If you’re using the Apollo Tooling extension for Visual Studio Code and you’re seeing an error about a self-signed certificate, it means that the extension is unable to establish a secure connection to the Apollo Studio API due to an issue with the certificate.

There are a few things you can try to fix this issue:

  1. Check the date and time on your computer. If the date and time are incorrect, it can cause issues with SSL certificates.
  2. Check your network connection. If you’re on a corporate network, there may be a firewall or proxy that is blocking the connection to the Apollo Studio API.
  3. If you’re running the Apollo Studio API locally, make sure that you’re using a trusted SSL certificate. You can use a tool like OpenSSL to generate a self-signed certificate.
