Setup

Certificates

You need a server certificate and corresponding private key to run demo-app.

An easy way to generate server certificate and key for local testing is mkcert.

Run mkcert to generate app.cacert.localhost.pem and app.cacert.localhost-key.pem:

mkcert -cert-file app.cacert.localhost

Configure the Demo Application

You will need a 32 byte and a 64 byte random secret for the session authentication and encryption keys:

openssl rand -base64 64
openssl rand -base64 32

You also need the client id and the client secret, that have been generated during the OIDC client setup described above.

Put the data into resource_app.toml:

[oidc]
client-id = "<client id from hydra clients invocation>"
client-secret = "<client secret from hydra clients invocation>"

[session]
auth-key = "<64 bytes of base64 encoded data>"
enc-key = "<32 bytes of base64 encoded data>"

Start

Now you can start the demo application:

make
./demo-app

Visit https://app.cacert.localhost:4000/ in a Browser and you will be directed through the OpenID connect authorization code flow.

Translations

This application uses go-i18n for internationalization (i18n) support.

The translation workflow needs the go18n binary which can be installed via

go install github.com/nicksnyder/go-i18n/v2/goi18n

To extract new messages from the code run

cd translations
goi18n extract ..

Then use

cd translations
goi18n merge active.*.toml

to create TOML files for translation as translate.<locale>.toml.

After translating the messages run

cd translations
goi18n merge active.*.toml translate.*.toml

to merge the messages back into the active translation files. To add a new language you need to add the language code to the languages configuration option (default is defined in the configmap in services/configuration.go).
