@kwiz/common

Shared TypeScript utilities used across KWIZ applications for Microsoft 365 and SharePoint development.

@kwiz/common provides reusable application-agnostic helpers for configuration, logging, authentication, cryptography, SharePoint REST, collections, promises, URLs, dates, types, and other common functionality.

Installation

npm install @kwiz/common

Requirements

• Node.js 16+

The published package targets ES2019 and supports both ES modules and CommonJS.

Application Configuration

Applications that use configuration-dependent functionality or shared logging should initialize @kwiz/common before those APIs are used.

import { config } from "@kwiz/common";

export const { GetLogger, configInfo } = config({
    BuildNumber,
    ReleaseStatus,
    ProjectName: "[my-project]"
});

Configuration Parameters

Property	Type	Purpose
BuildNumber	string	Identifies the current consuming application build.
ReleaseStatus	"dev" | "fastring" | "production" | "npm"	Identifies the runtime/release environment.
ProjectName	string	Prefix used to identify the consuming application in shared logging.

Environment flags are derived automatically from ReleaseStatus; they are not passed to config().

configInfo.IsLocalDev;
configInfo.IsFastRing;
configInfo.IsProduction;

The current mapping is:

ReleaseStatus	IsLocalDev	IsFastRing	IsProduction
"dev"	true	false	false
"fastring"	false	true	false
"production"	false	false	true
"npm"	false	false	true

Logging

The recommended way to obtain a logger is from the result of config():

import { GetLogger } from "./initCommon";

const logger = GetLogger("MyService");

logger.debug("debug message");
logger.info("information message");
logger.warn("warning message");
logger.error("error message");

config() also returns configInfo, which contains the normalized shared configuration.

The legacy logger(name) return value is deprecated; use GetLogger(name) instead.

Applications with Multiple Entry Points

If an application produces multiple independently loaded bundles, each entry point must ensure configuration has occurred before configuration-dependent code runs.

A shared bootstrap module is recommended:

// initCommon.ts
import { config } from "@kwiz/common";

export const { GetLogger, configInfo } = config({
    BuildNumber,
    ReleaseStatus,
    ProjectName: "[my-project]"
});

Then import it from each independently loaded entry point:

import "./initCommon";

If the bootstrap module is imported only for its side effect, make sure the consuming bundler does not remove it during tree shaking. For example:

{
    "sideEffects": [
        "./src/initCommon.ts"
    ]
}

Alternatively, expose an explicit initialization function and call it from each entry point.

Public Entry Points

The package currently exposes these supported entry points:

@kwiz/common
@kwiz/common/auth
@kwiz/common/crypto
@kwiz/common/sharepoint-rest

Root

Use the root package for general shared helpers, types, configuration, logging, and other common utilities:

import {
    config,
    CommonLogger,
    normalizeUrl,
    jsonParse,
    promiseAllSequential
} from "@kwiz/common";

The root entry point uses static exports so modern bundlers can remove unused modules.

Authentication

import {
    AutoDiscoverTenantInfo
} from "@kwiz/common/auth";

Cryptography

import {
    sign
} from "@kwiz/common/crypto";

SharePoint REST

import {
    GetList
} from "@kwiz/common/sharepoint-rest";

Use focused entry points for heavier functionality when possible. This keeps dependencies explicit and gives consuming bundlers a cleaner module graph.

Tree Shaking

@kwiz/common is published as both ESM and CommonJS and includes sideEffects metadata for modules that must be preserved.

For the best tree-shaking results:

• Prefer ESM in modern bundlers.
• Import only the functionality your application needs.
• Use focused package entry points for auth, crypto, and SharePoint REST functionality.
• Avoid importing unrelated modules solely for side effects.

Package Output

The package publishes:

lib/
    esm/      ES module output
    cjs/      CommonJS output
    types/    TypeScript declarations

The root package resolves to:

ESM:        lib/esm/index.js
CommonJS:   lib/cjs/index.js
Types:      lib/types/index.d.ts
