Installation

The SDK is delivered as the @techsign/kyc package. Pick the option that fits your project.

Your project	Recommendation
Plain HTML / PHP / .NET Razor	Copy the files to your server; use techsign-kyc.js (module) or techsign-kyc.iife.js
React	@techsign/kyc/react
Vue / Angular / other	@techsign/kyc + the custom element
Document only, no face	Any of the above + enable-face="false"

With npm

npm install @techsign/kyc

If the package was delivered to you as a folder or zip:

npm install ./vendor/techsign-kyc
# the folder must contain package.json and dist/

By copying the files to your server

Put the package contents under, for example, /sdk/:

/sdk/techsign-kyc.js
/sdk/chunks/...            ← required when using the module build
/sdk/techsign-kyc.iife.js  ← only when using the IIFE build

Package contents

File	When
techsign-kyc.js + chunks/	Recommended. Modern browsers, <script type="module"> or a bundler. When the face step is off, the face code is never downloaded.
techsign-kyc.iife.js	Older pages and a single <script> tag. One file with the face code included, so it is larger.
index.js + chunks/ + *.d.ts	npm and bundlers (Vite, Webpack): import '@techsign/kyc'
react.js + chunks/	React: import { TechsignKyc } from '@techsign/kyc/react'

Keep the chunks/ folder

With the module and npm builds, the chunks/ folder must sit next to the main file. Styles are bundled into the JavaScript; you don’t need to add any CSS.

TypeScript types are included in the package (CompleteDetail, ErrorDetail, SdkOptions, …).
