How to add a new source

We will use words source and fetcher. Сonsider them to be synonymous.

Select a name for the new source

First, you should select a name for your source. It should use kebab case, for example: source, good-source, the-best-source. Source name must be unique, because it will unambiguously identify your source.

Implementation

Implement source (fetcher)

Create a folder with a name of your fetcher in src/fetchers. Place the code of your fetcher inside of this folder and update src/fetchers/index.ts file to export your source. For more information check out BaseFetcher code and implementation of other fetchers, like coingecko, coingecko fetcher, and ecb.

Implement tests

We strongly recommend to implement tests for your fetcher. It's generaly a good practice and it will help you to avoid silly bugs in your code. You can find examples of tests for other fetchers in the test/fetchers folder.

Manifest(s)

  • Create a manifest with the name of the newly added fetcher and place it in the manifests folder
  • [Optional] If the source should be used in the main redstone provider, run node tools/manifest/generate-main-manifest.js

Sources config [optional]

Should I do this?

Sources config file is used in the RedStone web app. If you want your source to be visible there you should add it to config and update the app appropriately.

How to add a source to config

  • Add source details to the tools/config/predefined-configs/sources.json file
  • Run yarn build. It is required by generate-sources-config.js so it can work correctly
  • Run node tools/config/generate-sources-config.js to generate sources config. It will be saved to src/config/sources.json
  • Download logo for the newly created source
    • You can simply download it in browser and save as <SOURCE_NAME>.<IMG_EXTENSTION>
    • Or you can run node tools/cdn-images/download-source-logos.js, but it will download logos for all sources
  • Upload the source logo to RedStone CDN (manually through AWS S3 web interface)
  • Run node tools/cdn-images/update-sources-config.js to replace logo urls in sources config with redstone CDN urls
  • Update redstone-node dependency in redstone-app for being able to use the new source config file
