### Install Project Dependencies with npm

Source: https://github.com/lequant40/portfolio_allocation_js/blob/master/README.md

Installs the necessary project dependencies using npm. This is a prerequisite for compiling and testing the portfolio allocation algorithms.

```bash
npm install
npm install -g grunt-cli
```

### Calculate Risk Budgeting Weights in Node.js

Source: https://github.com/lequant40/portfolio_allocation_js/blob/master/README.md

This Node.js code snippet illustrates how to use the PortfolioAllocation library after installing it via npm. It first requires the library and then demonstrates calling the `riskBudgetingWeights` function with sample input data. This is a standard approach for using npm packages in a Node.js backend environment.

```javascript
var PortfolioAllocation = require('portfolio-allocation');
var w = PortfolioAllocation.riskBudgetingWeights([[0.1,0], [0,0.2]], [0.25, 0.75]);
```

### Compile Project Files for Development and Distribution

Source: https://github.com/lequant40/portfolio_allocation_js/blob/master/README.md

Compiles the project files for different environments. 'deliver-dev' generates files for browser or Node.js development, while 'deliver-dist' creates production-ready files.

```bash
grunt deliver-dev
grunt deliver-dist
```

### Calculate Risk Budgeting Weights in Browser

Source: https://github.com/lequant40/portfolio_allocation_js/blob/master/README.md

This HTML snippet shows how to include the PortfolioAllocation library in a web page using a CDN and then immediately use it to calculate risk budgeting weights. It assumes the library is loaded and accessible globally. The function `riskBudgetingWeights` is called with a sample covariance matrix and risk budgets.

```html
<script src="https://cdn.jsdelivr.net/npm/portfolio-allocation/dist/portfolio_allocation.dist.min.js" type="text/javascript"></script>
<script type="text/javascript">
  var w = PortfolioAllocation.riskBudgetingWeights([[0.1,0], [0,0.2]], [0.25, 0.75]);
</script>
```

### Compile Project Files for Google Sheets Integration

Source: https://github.com/lequant40/portfolio_allocation_js/blob/master/README.md

Generates project files specifically for integration with Google Sheets. This command ensures compatibility with the Google Sheets environment.

```bash
grunt deliver-gs
```

### Compute ERC Portfolio Weights in Google Sheets

Source: https://github.com/lequant40/portfolio_allocation_js/blob/master/README.md

This JavaScript function demonstrates how to compute Equal Risk Contribution (ERC) portfolio weights within Google Sheets. It takes a covariance matrix as input and utilizes the PortfolioAllocation library to calculate the weights, which are then returned to the spreadsheet. This function is intended to be used as a wrapper for Google Apps Script.

```javascript
function computeERCPortfolioWeights(covarianceMatrix) {
  // Note: The input range coming from the spreadsheet is directly usable.
    
  // Compute the ERC portfolio weights
  var ercWeights = PortfolioAllocation.equalRiskContributionWeights(covarianceMatrix);
  
  // Return them to the spreadsheet
  return ercWeights;
}
```
