Run a Point Network Node in a VS Code Debugger#

The VS Code debugger is configured using the VS Code launch config file. Its configured to launch a test node under your ~/.point/test1 directory.

To start the VS Code debugger, click on the debugger button and at the top select Launch Point Node from the drop down and hit the play button.

Now you can add breakpoints and run a depolyment from a separate terminal window to hit the breakpoint.

NOTE: The debugger may fail to start and this is usually due to the file still being present in the ~/.point/test1 directory. Simply delete that file (rm ~/.point/test1/ and run the debugger again.

NOTE: You might see an error when starting the debugger relating to a fastify plugin: Error: ERR_AVVIO_PLUGIN_TIMEOUT: plugin did not start in time. If you see this the debugger session will immediately stop. To fix this issue, you will need to comment out the fastify-nextjs plugin registration and web_routes lines in the ApiServer class and start the debugger again!

NOTE: The launch config makes use of the $HOME environment variable for the --datadir param. If you do not have this environment variable set, then you will need to do so and run the debugger again.

Attaching to a Point Network Node using Point Network console#

To attach to a node use the following (for example use the --datadir flag to specify Test 2):

./point attach --datadir ~/.point/test2

In the console REPL you can now issue commands to the node. For example, the command api ping will call the PingController#ping API endpoint:

> api pingQuerying http://localhost:2469/api/ping?{ ping: 'pong' }

To run a deployment via the Console you need to specify the absolute path of the site you want to deploy. For example, to deploy the example/hello.z site run the following command in the attached Point Network console (NOTE: change <ABSOLUTEPATHTO> to your absolute path):

> api deploy deploy_path=/<ABSOLUTEPATHTO>/pointnetwork/example/hello.zQuerying http://localhost:2469/api/deploy?deploy_path=/<ABSOLUTEPATHTO>/pointnetwork/example/hello.z{ status: 'success' }

Using the Point Network LevelDB Playground#

Under scripts/db there is a js file playground.js that can be used to test out interacting with the local LevelDB of one of the nodes.

To run this file, first stop the node you want to connect to (since LevelDB has a limitation of allowing only one connection at a time) and then run the script using node scripts/db/playground.js.

To change which Node LevelDB the script connects to, simply modify the const nodeid in the scripts/db/init.js and then run the playground.js script again.

The intention here is to be able to test out different LevelDB models that are available in the node using this 'playground'. So its possible to load any of the db/models and interact with the LevelDB.

For example, to use the File model:

require('./init')const File = require('../../db/models/file');... use the File model ...
