I'm trying to implement user email verification in my pet project with GraphQL and Node.js.
I already have signUp resolver which sends verification token but I've just understood that when a user clicks a link there is no way to send data from an email to the next GraphQL resolver which would use the token and verify the email.
So the question is: shall I make REST endpoint /verify
to do the work or there is a way to use /graphql
endpoint
If you use a separate /verify
endpoint, you'll most likely want to also redirect the user back to your site after processing the request. One approach would be to effectively reverse this flow, linking to your website and then having your page make the necessary GraphQL request.
Alternatively, you can invoke your verify
resolver through a link in the email. express-graphql
will handle both POST
and GET
requests. There's a couple of things to keep in mind with this approach though:
Here's a basic example:
const typeDefs = `
type Query {
verify: Boolean # Can be any nullable scalar
}
`
const resolvers = {
Query: {
verify: (root, args, ctx) => {
// Your verification logic
ctx.res.redirect('https://www.google.com')
}
}
}
const schema = makeExecutableSchema({ typeDefs, resolvers })
app.use('/graphql', graphqlHTTP((req, res) => ({
schema: MyGraphQLSchema,
graphiql: false,
// Inject the response object into the context
context: { req, res },
})))
app.listen(4000)
You can then just navigate to this url in your browser:
http://localhost:4000/graphql?query={verify}
