cosmos-sign

Utility library for signing Azure Cosmos tokens and generating headers. Works in both node and the browser

npm install cosmos-sign

Generate a signed header value using your master key

import { generateSignature } from "cosmos-sign"

const masterKey = "< your master key here >"
const method = "GET"
const resourceId = ""
const resourceType = ""

const result = generateSignature(masterKey, method, resourceType, resourceId)

Generate a headers object instead

import { generateHeaders } from "cosmos-sign"

const masterKey = "< your master key here >"
const method = "GET"
const resourceId = ""
const resourceType = ""

const headers = generateHeaders(masterKey, method, resourceType, resourceId)

fetch("https://your-db.cosmos.azure.com/", {
  headers
})

Optionally pass a date in

import { generateSignature } from "cosmos-sign"

const masterKey = "< your master key here >";
const method = "GET";
const resourceId = "";
const resourceType = "";
const date = new Date(<tomorrow>)

const result = generateSignature(masterKey, method, resourceType, resourceId, date);

Notes

See https://docs.microsoft.com/en-us/rest/api/cosmos-db/access-control-on-cosmosdb-resources for documentation on how to generate signatures
