@simpleview/sv-orion-client

sv-orion-client

Client for communicating with the sv-orion GraphQL system.

It is build in TypeScript and has one peer dependency of @simpleview/sv-graphql-client.

OS Support

The expectation is that this application will be installed in Linux using sv-kubernetes.

Prerequisites

• sv-graphql-client

Install

Using npm:

npm install @simpleview/sv-orion-client

Using yarn:

yarn install @simpleview/sv-orion-client

Update

To update to the latest version, rerun the install command.

Authentication Requirements

Interactions with sv-orion require authentication as a Simpleview user.

Use a Google Service Account when interacting with the service on behalf of a product.

const { AuthPrefix } = require("@simpleview/sv-auth-client");
const { GraphServer } = require("@simpleview/sv-graphql-client");

async function serviceAccountToken() {
	const service_account = JSON.parse(SERVICE_ACCOUNT_JSON);

	const { auth } = new GraphServer({
		graphUrl: AUTH_GRAPHQL_URL,
		prefixes: [AuthPrefix]
	});

	// authorize the service_account return the token
	const { token } = await auth.login_service_account({
		input: {
			email: service_account.client_email,
			private_key: service_account.private_key
		},
		fields: `
			success
			token
		`
	});

	return token;
}

The token should be added to the context for each function call.

Implementation & Usage

To see the input parameters and output fields of an endpoint, view the Schema in the GraphQL Explorer at https://graphql.simpleviewinc.com/ for the corresponding GraphQL query.

OrionPrefix

OrionPrefix can be loaded into the sv-graphql-client GraphServer to use as a client library for accessing orion in GraphQL.

JavaScript:

const { OrionPrefix } = require("@simpleview/sv-orion-client");
const { GraphServer } = require("@simpleview/sv-graphql-client");

module.exports = new GraphServer({ graphUrl: GRAPHQL_URL, prefixes: [OrionPrefix] });

TypeScript:

import { OrionPrefix } from "@simpleview/sv-orion-client";
import { GraphServer } from "@simpleview/sv-graphql-client";

export default new GraphServer({ graphUrl: GRAPHQL_URL, prefixes: [OrionPrefix] });

Where you are making server requests:

JavaScript:

const { orion } = require("./orionGraphServer");

TypeScript:

import { orion } from "./orionGraphServer";
