Calling Nebula graph from Browser JavaScript?

[lonnietc]

Hi All,

I'm very new to Nebula Graph but like graph databases and what to use it in a javascript browser extension to call a backend Nebula Graph server node that I will have running.

I also know about the Nebula Graph Node.JS libraries but I do not think that they can be used in a browser within JavaScript from what I understand.

Is there any drivers in JavaScript to call Nebula Graph?

Any help would be greatly appreciated.
Thanks in advance

Dear @lonnietc, welcome to the nebula community!

Native HTTP/RESTful interface is not yet supported for now(will be supported in the future).

For now, you can use the http-gateway, and you can reuse/refer to the nebula-studio project as well ;).

• https://nebula-graph.io/demo/ (playground of studio)

Thanks for getting back to my inquire and I will give it a try.

By the way, your demos do not seem to be connecting and give a connection refused error message in all of them.

I will try them again tomorrow to see if they work at that time.
Thanks again,
Lonnie

We are sorry the backend may be overloaded, will check with the guys maintaining this! Thank you!

Update: it's fixed now :)

Thanks and I will look into it more.

I did visit the demo's but it wants me to add data and for a new person trying to see what Nebula can do, I might suggest that you have some pre-canned demos with pre-populated data so that the visitor can see it already populated and start exploring since that is not what I see at all.

From what I am seeing, when I select, for example the "Basketball Player and Teams" demo it is not at all very initiative.

Will play around more to see if I can get a feel for things.
Thanks again

Dear @lonnietc,
We will improve the demo/demo system! Thanks a lot for your care and great idea on improvements.
The data itself had been imported already and it should be only explored for users but the guidance is not initiative(to make the user think the data was not yet imported).
Thank you!
