Prez UI is the front end of Prez - a linked data API.
Prez UI is a Vue.js single page application (SPA) that uses N3.js to process RDF data from the Prez API.
See the Prez UI demo website - https://rdflib.dev/prez-ui/
Configuring an instance of Prez UI is done by supplying environment variables.
Vite automatically imports environment variables from .env*
files with a preference order (see Vite Env Variables and Modes), where .env.[mode].local
will be preferenced over .env.[mode]
files for example, where [mode]
would be development
, production
, etc. For convenience for local development, it is recommended to create a .env.development.local
file to set your local environment variables.
See .env
for the default values for the available environment variables. Note that environment variables must be prefixed with VITE_
.
Prez UI instances can be themed by providing header & footer HTML files, as well as custom CSS styling. After building your instance of Prez UI (before which your environment variables must be set):
npm install
npm run build
copy your files into the dist/theme/
directory, overriding existing files when necessary. See the public/theme/
folder for the required files:
favicon.ico
header.html
footer.html
theme.css
These files should be left blank if not being used.
The public/style.css
CSS file contains CSS variables that can be overridden in your theme.css
file for easy theming.
Prez container images are available here.
The image name is ghcr.io/rdflib/prez-ui
.
The latest
tag points to the latest stable release of Prez. All latest stable releases have a major, major and minor, and major, minor and patch tag pointing to it.
For example, for a release with a git tag of 3.2.4, the following tags will be on the container image:
3
3.2
3.2.4
latest
New commits to the main
branch creates a rolling dev image with the dev
tag. The dev builds will also include a tag in the form of major.minor.{patch+1}-dev.{commits-since-last-release}.{short-commit-sha}. This conforms to semantic versioning and will be recognised by orchestration systems to perform automatic releases.
For example, if the latest release is 3.2.4 and there has been 7 new commits since the release and the short commit SHA is fc82562, then the container image tag will be:
3.2.5-dev.7.fc82562
Prez UI can be deployed as a Docker container, which contains an NGINX server serving static files. To theme your Docker container, create a volume at /app/theme
called theme/
containing the theming files, e.g.:
docker run -v <YOUR_THEME_FOLDER>:/app/theme rdflib/prez-ui
To enable SSL for a Docker container deployment, supply your own nginx.conf
file containing the commented-out lines for SSL in the supplied nginx.conf
file in a Docker volume (yet to be implemented).
