Cryostat-Web

Web front-end for Cryostat, providing a graphical user interface for managing JFR on remote JVMs.

Based on Patternfly React Seed.

SEE ALSO

• cryostat-core for the core library providing a convenience wrapper and headless stubs for use of JFR using JDK Mission Control internals.

• cryostat-operator for an OpenShift Operator facilitating easy setup of Cryostat in your OpenShift cluster as well as exposing the Cryostat API as Kubernetes Custom Resources.

REQUIREMENTS

Build:

• NPM
• Yarn

BUILD

Setup dependencies

npm install --save-dev yarn # or install using your package manager
npm run yarn:frzinstall # or just yarn install, if installed globally

Run a production build

npm run build

DEVELOPMENT SERVER

To run a hot-reloading instance of cryostat-web, first run a cryostat instance with WebSocket communication and CORS enabled. Use CRYOSTAT_CORS_ORIGIN to target http://localhost:9000

For example: cd /path/to/cryostat && CRYOSTAT_DISABLE_SSL=true CRYOSTAT_CORS_ORIGIN=http://localhost:9000 sh run.sh

Then run npm run start:dev. This will target the cryostat instance started above by default. This can be customized by editing the .env file, for example if you have another service already listening on the default port 8181 and your Cryostat is listening elsewhere.

TEST

Run the test suite

npm run test

Run the linter

npm run lint

Run the code formatter

npm run format

Inspect the bundle size

npm run bundle-profile:analyze

Start the express server (run a production build first)

npm run start
