Client libraries includes methods to use SHIELD, libraries to ease the use of Webpack Module Federation - Promise based loading. It provides the essential packages to facilitate appblocks features across appblocks applications.
As of now, js-sdk contains the following
shield helps to setup authentication for your application. It contains many methods to setup user authentication with shield and obtain tokens across appblocks applications.
ab-federation-helpers contains hooks and methods to facilitate federated Components and Modules
npm i @appblocks/js-sdk
import { shield } from '@appblocks/js-sdk'
import { useFederatedComponent } from '@appblocks/js-sdk'
js-sdk/shield includes the following elements
- tokenStore
- init
- verifyLogin
- verifyLoginWithoutRedirect
- getAuthUrl
- logout
- logoutWithoutRedirect
- validateAccessToken
Its an object which stores the token, refresh Token, expiry time as private variables along with related functions. It contains the timer id for the token
shield.tokenStore.getToken()
Its used to initialise the tokenstore with values from the shield backend. It takes a parameter clientID which is unique for each application.
await shield.init('#client-id')
It retrieves for the token from the localStorage and validates the token. If the token is not valid it redirects to the shield login.
const isLoggedinn = await shield.verifyLogin()
It retrieves for the token from the localStorage and validates the token. If the token is not valid it checks for valid cookie and tries to login, else continues as not logged in and does not redirect.
const isLoggedinn = await shield.verifyLoginWithoutRedirect()
It generates authorization URL with query parameters
const authUrl = shield.getAuthUrl()
It logs out the user by removing the token from localStorage and redirects to shield login.
await shield.logout()
It logs out the user by removing the token from localStorage but does not redirect to shield
await shield.logoutWithoutRedirect()
It checks the validity of the token.It can be used to check if user is logged in or not.
await shield.validateAccessToken()
ab-federation-helpers includes the following elements
used to obtain federated Component .
const system = {
module: './login',
scope: 'login',
url: 'http://localhost:3013/remoteEntry.js',
}
const { Component: FederatedComponent, errorLoading } = useFederatedComponent(
system?.url,
system?.scope,
system?.module,
React
)
return (
<React.Suspense fallback={''}>
{errorLoading
? `Error loading module "${module}"`
: FederatedComponent && <FederatedComponent />}
</React.Suspense>
)
used to obtain federated Module .
const system = {
module: './login',
scope: 'login',
url: 'http://localhost:3013/remoteEntry.js',
}
const { Component: FederatedModule, errorLoading } = useFederatedModule(
system?.url,
system?.scope,
system?.module,
React
)
loads script from remote URL.
const { ready, errorLoading } = useDynamicScript(remoteUrl, React);
