# 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
|
|
```
