Zero-config HTTP server as Express.js to facilitate development
Zero-config HTTP server as Express.js to facilitate development.
This package is primarily built for HTTP servers used by Custom Applications and it provides a set of components to facilitate the development of the HTTP server.
$ npm install --save @commercetools-backend/express
This Express.js middleware should be used to handle the authentication exchange between the server and the /proxy/forward-to
endpoint of the Merchant Center API Gateway.
You can read more about the "Proxy to External API" concepts here.
const {
createSessionMiddleware,
CLOUD_IDENTIFIERS,
} = require('@commercetools-backend/express');
app.use(
createSessionMiddleware({
audience: 'https://my-api-server.com',
issuer: CLOUD_IDENTIFIERS.GCP_EU,
})
);
app.use((request, response, next) => {
// `request.session` contains the useful information
});
audience
(string): The public-facing URL of your API server. The value should only contain the origin URL (protocol, hostname, port), the request path is inferred from the incoming request.
issuer
(string): Either a cloud identifier or a valid URL to the Merchant Center API Gateway. The cloud identifier maps to the Merchant Center API URL of the related cloud region.

inferIssuer
(boolean): Determines whether the issuer should be inferred from the custom request HTTP header x-mc-api-cloud-identifier
which is sent by the Merchant Center API Gateway when forwarding the request. This might be useful in case the server is used in multiple regions.
jwks
(object): See options of jwks-rsa
.
If your HTTP server runs as a Serverless Function, the Express.js middleware should not be needed. Instead you can use the underlying function that does not require the next
callback.
Example for Google Cloud Functions
const {
createSessionAuthVerifier,
CLOUD_IDENTIFIERS,
} = require('@commercetools-backend/express');
const sessionAuthVerifier = createSessionAuthVerifier({
audience: 'https://my-api-server.com',
issuer: CLOUD_IDENTIFIERS.GCP_EU,
});
exports.handler = async function (request, response) {
try {
await sessionAuthVerifier(request, response);
} catch (error) {
response.status(401).send(JSON.stringify({ message: 'Unauthorized' }));
return;
}
// `request.session` contains the useful information
};
The same concept applies for serverless functions in other cloud providers.
