#Financial calculator

This is reactjs application recalculates financing options using financial api. Library uses react, typescript, css written in SASS preprocessor.

Developing bundler is webpack.

Build production build made as simple tsc compilation with asset files copies provided

##Requirements - nodejs v10 + - npm v6.9.0 +

##Installation: Installing dependencies

For properly installing depedencies you need to prepare whole repository from its ROOT directory, calling lerna commands

For preparing needed devDepedencies on top level

npm install

Installing dependencies in each package

lerna bootstrap

###Build process

Build task builds two types of library entrypoints :

• "web" - destined to web include (for example by script tag) with all depedencies built in (like react and other third party libraries)

• "ecma script module" - destined for further bundler processing, it is resolved through simply typescript compiling in package.json statement

  tsc && copyfiles "./lib/**/*.!(tsx|ts|d.ts|html)" "dist/esm" -u 1
  

##Development

Be sure, that all "file" linked depedencies, has their dist directories, if not - call commands from repository ROOT directory

lerna bootstrap
lerna run build

Running dev server in standalone mode for current library

lerna run start --stream --scope @dac-software/financial-calculator

Running dev mode through bundler in other project. Project should be linked by npm.

lerna run build:dev --scope @dac-software/financial-calculator

build dev emmits files into dist/esm/offer-financial-calculator without CSS / files extraction, it is determined by webpack condition on compilation mode

##Running tests

Allowed only from root directory

npm run test

####Codestyle

We are in consonance with standardjs. Call commands from repository ROOT directory

Validation codestyle:

lerna run codestyle-check-typescript

Automatic fix:

lerna exec npm run codestyle-typescript-fix
