How to use nebula CLI in your visualization

You can use the package.json script variant of these commands, which are exposed for you withnebula create

When you want to make the nebula serve, nebula build, and nebula sense commands available in your visualization by yourself, run the following command.

npm install @nebula.js/cli @nebula.js/cli-build @nebula.js/cli-sense @nebula.js/cli-serve


yarn add @nebula.js/cli @nebula.js/cli-build @nebula.js/cli-sense @nebula.js/cli-serve

Open up your package.json, those dependencies are added.

  "devDependencies": {
    "@nebula.js/cli": "1.7.0",
    "@nebula.js/cli-build": "1.7.0",
    "@nebula.js/cli-sense": "1.7.0",
    "@nebula.js/cli-serve": "1.7.0"

and add a script like so:

"scripts": {
    "build": "nebula build",
    "start": "nebula serve",
    "sense": "nebula sense"

You can also run nebula cli commands with Node.js. Create a js file called build.js and add the following:

const build = require('@nebula.js/cli-build');
const sense = require('@nebula.js/cli-sense');

await build({
  config: '../nebula.config.js',
  sourcemap: false,
  core: 'core',
  mode: 'production',
  watch: false,
await sense({ output: 'sn-table-ext', sourcemap: true });

and run the following command:

node build.js

cd commands/cli
node lib/index.js -h

Test nebula CLI globally

From the commands/cli directory, run the following command to create a global symlik to the binary:

Run the following command to remove the symlinked nebula and run 'yarn link' again:

yarn unlink
