@thing-description-playground/WEB

This package provides the web interface of the Web of Things Thing Desciption Playground. It uses the functionality of the core package to validate Thing Descriptions and assertions to generate an assertion Test report. You can find more information about the Thingweb-Playground here.

The TDs can be exported as URLs which can be copied anywhere and reopened here.

Browser based Thing Description Validation

• Online: It is hosted here

  • Simply paste a TD in the text field and click validate
  • Safari browser has unexpected behavior with JSON-LD documents
  • I you loose your internet connection when validating JSON-LD validation will fail since it tries to access the documents under @context (can be turned off)

• Offline/OnPremise: by hosting the web yourself. You can use the web package to host/adapt your own browser version of the WoT playground.
  To host it yourself please read the section Deployment.

(Playwright) Testing

For testing the package has to be installed with npm install (no production only option set).

You can check if the website created by this package is visually okay and functionally working correctly by running npm test and inspecting the results in the test-results folder.

To debug the playwright test (and see what actions it triggers) use npm start debug.

To host the website for test purposes use npm run serve.

Deployment

There are two ways to deploy the thing-description-playground as a web application. The example below explains the deployment (which can be easily automized) for both versions assuming nginx as a web-server. Using --only=production option speeds up the process and is not necessary, also it does not allow running tests (because the testing dependencies are devDependencies). Please remember that in any case the files need to be delivered by a webserver (also for localhost), simply opening index.html with a browser won't be enough.

As a Package

Setup

1. Create an empty NPM package
2. Install @thing-description-playground/web as a dependency
3. Install the production dependencies of @thing-description-playground/web
4. Copy the folder content to your web-directory

mkdir empty-package
cd empty-package
npm init
npm install @thing-description-playground/web
cd ./node_modules/@thing-description-playground/web
npm install --only=production
cp -r ./ ./var/www/html/subdir/

Update

1. Open the created package
2. Update its dependencies (which is only @thing-description-playground/web)
3. Install the production dependencies of @thing-description-playground/web again
4. Copy the folder content to your web-directory

cd empty-package
npm update
cd ./node_modules/@thing-description-playground/web
npm install --only=production
cp -r ./ ./var/www/html/subdir/

As repository

Requires Lerna to be installed globally (npm install -g lerna).

1. Clone the repo
2. Install the monorepo (allows linking unpublished versions).
3. Install the web package locally to ensure that e.g. core dependency is not just a symlink (loading e.g. examples wouldn't work otherwise)
4. Clean the target dir (nginx web-directory)
5. Copy the folder content to your web-directory
6. Clean the checked out files

git clone [e-mail]:thingweb/thingweb-playground.git
cd thingweb-playground
lerna bootstrap
cd ./packages/playground-web
npm install
rm -r -f /var/www/html/subdir/*
cp -r ./* /var/www/html
cd ../../../
rm -r -f thingweb-playground
