Graphcool released it’s GraphQL command-line tools two days ago, so I thought it would be nice to see how well they work, especially with our Neo4j GraphQL backend. And here’s the good news : pretty well.You can see a quick demo below which this article will explain in detail.
So installing is easy, it’s just
npm install -g graphql-cli
, which makes a graphql
command available. The tools make use of graphql-config
, a consistent way of storing endpoints and related configuration information in YAML or JSON, which is specified here.Here is a quick overview of the commands available:
Example GraphQL Backend
As an example for my tests of the GraphQL command-line interface, I’ll use my Game of Thrones GraphQL backend.
(If you just want to test it out, you can also just run
npm install -g neo4j-graphql-cli && neo4j-graphql
to spin up the default movie database backend.)After spinning up my Game of Thrones instance I find this connection information on my Neo4j Sandbox UI:
GraphQL-CLI Setup
So I can just run
graphql init
, which then nicely asks me for these things:Authentication Headers !?!
All good so far. But when I try to run
graphql ping
I get this error message, which means that (of course) my authentication header is missing.Unfortunately at 3 a.m. I didn’t think about looking through the
graphql-config
spec, so I delved into the code of graphql-cli
and then graphql-config
, looking for a place to add header information.Read the rest of Michael’s post on Medium where he covers plugin options, schema feching and altering current schemas.
