# UDF Compatible Datafeed This folder contains [UDF](https://github.com/tradingview/charting_library/wiki/UDF) datafeed adapter. It implements [JS API](https://github.com/tradingview/charting_library/wiki/JS%20API) and makes HTTP requests using [UDF](https://github.com/tradingview/charting_library/wiki/UDF) protocol. You can use this datafeed adapter to plug your data if you implement [UDF](https://github.com/tradingview/charting_library/wiki/UDF) on your server. You can also scrutinize how it works before writing your own adapter. This datafeed is implemented in [TypeScript](https://github.com/Microsoft/TypeScript/). ## Folders content - `./src` folder contains the source code in TypeScript. - `./lib` folder contains transpiled in es5 code. So, if you do not know how to use TypeScript - you can modify these files to change the result bundle later. - `./dist` folder contains bundled JavaScript files which can be inlined into a page and used in the Widget Constructor. ## Build & bundle Before building or bundling your code you need to run `npm install` to install dependencies. `package.json` contains some handy scripts to build or generate the bundle: - `npm run compile` to compile TypeScript source code into JavaScript files (output will be in `./lib` folder) - `npm run bundle-js` to bundle multiple JavaScript files into one bundle (it also bundle polyfills) - `npm run build` to compile and bundle (it is a combination of all above commands) NOTE: if you want to minify the bundle code, you need to set `ENV` environment variable to a value different from `development`. For example: ```bash export ENV=prod npm run bundle-js # or npm run build ``` or ```bash ENV=prod npm run bundle-js ``` or ```bash ENV=prod npm run build ```
