How to use

Install package from NPM

npm install ydb-sdk

Install dependencies and compile library

npm ci
npm run build

Set environment variables

Variables which should not be set for a specific installation are explicitly set to an empty value, so that startup script correctly detects which installation you are aiming at.

Common variables

export YDB_SDK_LOGLEVEL=debug
export IAM_ENDPOINT= # for Yandex.Cloud, by default it is iam.api.cloud.yandex.net:443

For the typical cases of using these variables, see below:

export YDB_ACCESS_TOKEN_CREDENTIALS= # here comes your token from `yc iam create-token`

export YDB_ANONYMOUS_CREDENTIALS=1 # try anonymous access

export YDB_METADATA_CREDENTIALS=1 #  try local metadata service authentication

export YDB_SERVICE_ACCOUNT_KEY_FILE_CREDENTIALS = # here should be the path to the service account key file from 'yc iam key create --folder-id <folder_id> --service-account-name <sa_name> --output ~/.ydb/sa_name.json'
