Orbital TypeScript client

A library to execute TaxiQL queries against the Orbital query server.

Getting started

Install the dependency with

npm install @orbitalhq/orbital-client

and create a file called orbital.config.json to the same folder that contains package.json with the following content:

{
  "orbitalServerUrl": "<SCHEMA_SERVER_URL>"
}

where you replace <SCHEMA_SERVER_URL> with the URL of the schema server like http://schema-server.orbital.example.com.

Finally, run

npm run orbital:taxonomy:generate

This will generate a taxonomy file called taxonomy.ts next to package.json. This file should be committed to version control and be updated (by re-running npm run orbital:taxonomy:generate) whenever the schema changes.

Once the taxonomy file is generated, you can initialize the client:

import { asArray, buildClient, consoleLogger, HttpQueryClient } from 'orbital-client';
import { taxonomy } from './taxonomy';

const client = buildClient<{}, typeof taxonomy>(
  taxonomy,
  new HttpQueryClient('http://localhost:9022'),
  {
    logger: consoleLogger,
  },
);

and start executing queries

client
  .given(taxonomy.people.FirstName, 'John')
  .find(asArray(taxonomy.people.Person))
  .execute()
  .subscribe((result) => console.log(result[0].firstName));

which sends the following TaxiQL query to be executed on the Orbital server:

given {
        people.FirstName = "John"
}
find { people.Person[] }

You can also access this query by calling .toTaxiQL() on the query builder.

const query = client
  .given(taxonomy.people.FirstName, 'John')
  .find(asArray(taxonomy.people.Person))
  .toTaxiQl();
console.log(query);
