initAmplifySDK

All Amplify SDK functions require initialization before use. Call initAmplifySDK() once at application startup.

Import

import { initAmplifySDK } from "@paxoslabs/amplify-sdk";

Usage

await initAmplifySDK("pxl_your_api_key");

Parameters

Parameter	Type	Required	Description
`apiKey`	`string`	Yes	Your Paxos Labs API key (format: `pxl_...`)
`options`	`SDKInitOptions`	No	Configuration options for telemetry and logging

SDKInitOptions

interface SDKInitOptions {
  /** Enable/disable PostHog telemetry (default: true) */
  telemetry?: boolean;

  /** Log level for SDK operations (default: LogLevel.ERROR) */
  logLevel?: LogLevel;

  /** Custom logger implementation */
  logger?: Logger;
}

Option	Type	Default	Description
`telemetry`	`boolean`	`true`	Enable PostHog error tracking
`logLevel`	`LogLevel`	`LogLevel.ERROR`	Minimum log level to output
`logger`	`Logger`	Built-in console logger	Custom logger implementation

Return Type

Promise<void>

Examples

Basic
With Options
Custom Logger

import { initAmplifySDK } from "@paxoslabs/amplify-sdk";

await initAmplifySDK("pxl_your_api_key");

import { initAmplifySDK, LogLevel } from "@paxoslabs/amplify-sdk";

await initAmplifySDK("pxl_your_api_key", {
  telemetry: false,
  logLevel: LogLevel.DEBUG,
});

import { initAmplifySDK, LogLevel } from "@paxoslabs/amplify-sdk";

await initAmplifySDK("pxl_your_api_key", {
  logLevel: LogLevel.DEBUG,
  logger: {
    debug: (msg, ctx) => console.debug(`[SDK] ${msg}`, ctx),
    info: (msg, ctx) => console.info(`[SDK] ${msg}`, ctx),
    warn: (msg, ctx) => console.warn(`[SDK] ${msg}`, ctx),
    error: (msg, ctx) => console.error(`[SDK] ${msg}`, ctx),
  },
});

Behavior

Validates API key - Ensures key follows expected format (pxl_...)
Pre-populates cache - Fetches vaults and assets during initialization
Configures telemetry - Sets up PostHog if enabled
Configures logging - Sets log level and optional custom logger
Idempotent - Multiple calls with same key are no-ops
Re-initialization - Different key clears cache and reconfigures

Error Handling

try {
  await initAmplifySDK("pxl_your_api_key");
} catch (error) {
  if (error.code === "INVALID_API_KEY") {
    console.error("Invalid API key format");
  }
}

Error Code	Description	Resolution
`SDK_NOT_INITIALIZED`	SDK used before `initAmplifySDK()`	Call `initAmplifySDK()` first
`INVALID_API_KEY`	API key validation failed	Check API key format
