The instructions in this article are applicable only if you want to tinker with the LuciadRIA sample code yourself.
To start the LuciadRIA samples as they come in the release, without modification, start the sample server with the
Make sure your system setup covers all prerequisites, as described in the installation instructions.
npm installin the root of the LuciadRIA distribution.
As a result, all sample dependencies are installed. You have to install these only once for the release. See Bootstrapping dependencies.
Start the sample server with the
startSampleServerscript in the root of the LuciadRIA distribution. See Running the sample server for more information.
npm run devin the directory of the sample you want to edit and run.
A browser window opens automatically. It runs your sample and watches the files in that directory. If you edit and save a file in that directory, the running sample changes automatically, and the browser window refreshes. See Running a webpack dev-server for a sample.
Before you can deploy the samples in the
samples/ directory, you must install all dependencies of the
LuciadRIA distribution and its individual samples. To install the dependencies, you must execute
npm install in the root of the LuciadRIA distribution. This command first installs all development dependencies declared in the root
package.json, and then executes
lerna bootstrap, through a post-install script. The lerna bootstrap links the local dependencies of all samples to the correct packages and
installs all external npm dependencies in the correct
Lerna also takes care of dependency hoisting: dependencies that are common to
different samples are only installed once in a higher-level
After bootstrapping the dependencies of all samples, you can set up your web application.
Several samples do not fetch their data locally, but request it from a server, or use other data services. In the
LuciadRIA distribution, a sample server is provided to host those services. You can run the sample server by executing the
startSampleServer script. The server is hosted on http://localhost:8072 by default.
When you are developing an application, it is useful to run a development server, or dev-server. A development server serves the application and watches the source files for changes. It will serve those changes without a server restart. To start a webpack dev-server for a sample application in the LuciadRIA distribution:
Make sure you have bootstrapped the sample dependencies, as explained in Bootstrapping dependencies.
Go to the
samples/directory and execute
npm run dev.
By default, a dev-server starts hosting the First Sample on
http://localhost:3001/. It also watches the bundled files so that any changes in the source code or styling are picked up and served as long as the dev-server is running.
You can also add arguments to
npm run dev by adding
-- and one or more argument tags at the end:
Specify the port on which the webpack dev-server will run.
Set this argument to run the sample using a WebGL map.
Set this argument to run the sample using a 3D WebGL map.
Specifies the URL (and port) on which the sample server is running.
Specifies the URL (and port) on which the LuciadFusion server is running.
The webpack configuration file of all samples extends from
the webpack configuration web page for more information.
When you are deploying a real application, just running the provided webpack dev-server will not suffice. You will need to take care of other steps, such as minification/uglification or chunk splitting as well, before you can serve the application.
Building and running samples may require a significant amount of memory. To execute the build, you need to configure
the amount of memory that Node.js can use. You can do so by setting the NODE_OPTIONS environment variable to
To build and run the application, take these steps:
npm run buildcommand in the sample directory.
The sample is packaged to
The original sample in that directory will be overwritten, so it might be a good idea to back that up first.
Start the sample server by running the
Open your browser, and point it to
http://localhost:8072/samples/<sample>. A new web page displays your application.
This uses the same webpack configuration file as discussed in Running a webpack dev-server for a sample.
