fulcrum-expressions v2.1.0

Fulcrum Expressions

This implements the runtime for javascript expressions in Fulcrum.

The current implementation uses coffeescript.

There is a typescript implementation (latest version is likely in fulcrum-components/src/expressions, but there is also a typescript branch on this repo) that is currently being used in fulcrum-components to provide types to the monaco editor used to edit data events, calculations, etc. Eventually, this repo should contain that implementation, and ideally move off the coffeescript implementation once we are confident the typescript implementation works. Right now, we haven't determined the best way to distribute those types from this package. Until then, any type updates that need to be made (new public facing functions or otherwise) will need to be made in the typescript implementation.

Setup

Install dependencies

yarn

Build

Build expressions.js and sandbox (expressions-proxy.js and expressions.html)

yarn build

Build debug versions

yarn build:debug

Generate Documentation

Make changes to docs.js and event_docs.js.

yarn build:docs

Distribute

Builds everything for distribution

yarn build:dist

Tests

yarn test

Console

Starts an interactive node terminal with the functions available to call

yarn console

Deploy

Currently all projects pull the expression.js lib produced by this repo from https://assets.fulcrumapp.com/expv1/expressions.js. Until we are able to move projects over to using the published npm library, we will need to manually deploy by copying the dist/expressions.js file to that S3 bucket for others to see changes.

To deploy to your user's preview environment:

aws sso login (or however you login to the chaos aws account)
yarn deploy

(Remember to update fulcrum's config to point at your S3 bucket's files)

To deploy to production (requires fulcrum production access):

aws sso login (or however you login to the readonly fulcrum aws account)
yarn deploy production

Please be careful while doing this, as there aren't many guardrails in place at the moment. If unsure, ask.

Documentation

Documentation is handled using jsdoc, with functions documented in the source file here.

Deprecated Info (NOT USED, AND PROBABLY DOESN'T WORK, BUT LEFT FOR REFERENCE)

Copy files to other repositories

Copies the build output and docs to the other repositories (each are optional, but at least one is needed).

You can define the paths to the Fulcrum repos using environment variables in your shell config:

export FULCRUM_ANDROID=/path/to/android/app
export FULCRUM_IOS=/path/to/ios/app
export FULCRUM_WEB=/path/to/web/app
export FULCRUM_DEV_SITE=/path/to/website

Or you can assign them in the yarn command:

FULCRUM_DEV_SITE=$HOME/dev/fulcrumapp.com yarn build:dist && yarn copy

Once you have the environment variables set, you can run:

yarn copy

or

yarn build:dist && yarn copy # clean, build and deploy everything
