Question 1

How do I authenticate with githubv4 using a personal access token?

Accepted Answer

Use the golang.org/x/oauth2 package to create an http.Client with your token, then pass it to githubv4.NewClient. The README provides a step-by-step example with StaticTokenSource for quick setup.

Question 2

githubv4 vs go-github: which one should I use for my Go project?

Accepted Answer

Choose githubv4 if you need GraphQL's flexibility for complex queries or real-time data; go-github is better for REST-based operations or if you prefer a simpler, more established wrapper for common tasks.

Question 3

How to handle errors when querying with githubv4?

Accepted Answer

Check the error returned by client.Query or client.Mutate; common issues include authentication failures or GraphQL schema mismatches, so ensure variables and structs match the API documentation.

Question 4

Can I use githubv4 with GitHub Enterprise?

Accepted Answer

Yes, use githubv4.NewEnterpriseClient with your GitHub Enterprise endpoint URL and an authenticated http.Client, as detailed in the authentication section of the README.

Question 5

What's the best way to paginate through GitHub issues using githubv4?

Accepted Answer

Define a query struct with PageInfo fields, use cursor variables in arguments, and loop until HasNextPage is false, as shown in the pagination example to fetch all comments efficiently.

Question 6

How to define custom scalar types for GraphQL variables in githubv4?

Accepted Answer

Use githubv4-provided types like githubv4.String in your variables map, or implement json.Unmarshaler for custom conversions, ensuring compatibility with GitHub's scalar definitions.
