Initialize the API Client

Note: Documentation for the client can be found here.

The following parameters are configurable for the API Client:

| Parameter | Type | Description | | --- | --- | --- | | timeout | number | Timeout for API calls.Default: 0 | | httpClientOptions | Partial<HttpClientOptions> | Stable configurable http client options. | | unstableHttpClientOptions | any | Unstable configurable http client options. | | bearerAuthCredentials | BearerAuthCredentials | The credential object for bearerAuth |

The API client can be initialized as follows:

Code-Based Client Initialization

import { Client } from 'tesser-api-sdk';

const client = new Client({
  bearerAuthCredentials: {
    accessToken: 'AccessToken'
  },
  timeout: 0,
});

Configuration-Based Client Initialization

import * as path from 'path';
import * as fs from 'fs';
import { Client } from 'tesser-api-sdk';

// Provide absolute path for the configuration file
const absolutePath = path.resolve('./config.json');

// Read the configuration file content
const fileContent = fs.readFileSync(absolutePath, 'utf-8');

// Initialize client from JSON configuration content
const client = Client.fromJsonConfig(fileContent);

See the Configuration-Based Client Initialization section for details.

Environment-Based Client Initialization

import * as dotenv from 'dotenv';
import * as path from 'path';
import * as fs from 'fs';
import { Client } from 'tesser-api-sdk';

// Optional - Provide absolute path for the .env file
const absolutePath = path.resolve('./.env');

if (fs.existsSync(absolutePath)) {
  // Load environment variables from .env file
  dotenv.config({ path: absolutePath, override: true });
}

// Initialize client using environment variables
const client = Client.fromEnvironment(process.env);

See the Environment-Based Client Initialization section for details.
