Customizing HTTP endpoints

You can customize the HTTP endpoints by adding comments to the queries.

-- http: Method Path

Here’s an example of a queries file that has a custom HTTP endpoint:

-- name: ListAuthors :many
-- http: GET /authors
SELECT * FROM authors
ORDER BY name;

-- name: UpdateAuthorBio :exec
-- http: PATCH /authors/{id}/bio
UPDATE authors
SET bio = $1
WHERE id = $2;

Editing the generated code

It's safe to edit any generated code that doesn't have the DO NOT EDIT indication at the very first line.
After modify a SQL file, execute these commands below:

sqlc generate
go generate
