Js-graphql-intellij-plugin: No syntax highlighting in .graphqls files in IntelliJ IDEA

[vojtechmasa]

Hi,
I might probably misconfigured something, but syntax hightlighting doesn't work for me for .graphqls files. Also, even if I write something syntactically incorrect, the green tick - syntactic analysis - is still displayed. I've set up graphql.config.json according to the docs. Version of IntelliJ IDEA: 2016.3. I am attching a screenshot.

Hi.

Thanks for using the plugin.

Two questions:

• Does the highlighter work in .graphql files?
• What's the output in the Console tab of the GraphQL tool window

Hi,
thanks for your message. Renaming to .graphql didn't help. But here is the output of the console

\...\.IntelliJIdea2016.3\config\plugins\js-graphql-language-service.dist.js:9
let app = require('../src/languageservice');

Which version of Node.js are you using? I've tested on Node 4 and newer versions should also work fine.

Regarding the .graphqlextension, that was simply to narrow down what the problem is. You should write the schema in .graphqls.

Great work, loving the idea
I am facing the same issue in Intellij on Ubuntu (Apollo), this is my observation so far:
1 - if i copy the generated .graphqls schema to a new file with the same extension inside the project then it will not recognise it ...until...
2 - i press enter/new line ..then it works

@jimkyndemeyer Sorry, I had some prehistoric version of Node installed (0.12) - I don't use Node, but only java API in GraphQL (in fact originaly I was not even aware that NodeJS is required for this plugin). Unfortunately, the upgrade to node 6.10.3 didn't help, the highlighting still doesn't work. I also tried to uninstall / install the plugin in IntelliJ + restart. Now, when I open a *.graphqls file, I can see only tabs "Current Errors" and "Query Result", both empty.
@amirhakim unfortunately didn't help for me
Thanks a lot (in advance)!

Can you check the following:

• In the Node.js settings, that the Node 6 interpreter has been set as the default -- if not, set it and restart IDEA
• In the bottom right, that there's no red blinking error icon -- and if there is, please click it and paste the stacktrace in this issue

Thanks,
Jim.

Jim, setting the default Node interpreter helped. Thanks a lot for your help!

[jimkyndemeyer]

Great. Glad I could help.

@amirhakim suggestion helped to realise that the plugin won't highlight graphqls file if it's named "schema.graphqls". Rename it to anything else and it will highlight it
