Unofficial API

This project is neither created nor endorsed by Yahoo Inc. Yahoo does not provide any official API to developers, nor makes any guarantees regarding service availability or API consistency. In practice however, the open source community has kept this project (and it's predecessor) working well since 2013.

Nevertheless, we make no guarantees and you use this package at your own risk. The developers (and obviously Yahoo) cannot be held responsible for any losses you may incur as a result of using this service. Use of this package is considered acknowledgement and acceptance of these terms and of it's license.

(Optional) TypeScript Love

Working with yahoo-finance2 is a joy if you're using TypeScript (but you don't have to), with type checking and auto completion:

Try it yourself on our Live CodeSandbox.

Devel Mode

In "devel" mode, any URL will only be fetched once and cached in memory and on the disk. All future requests (for the rest of time) will return the cached result. This is very helpful to speed up development and is used extensively for our tests.

await search('AAPL', {}, { devel: true });                // uses sha1 from URL
await search('AAPL', {}, { devel: 'search-AAPL.json' });  // fixed filename

Note: require('yahooFinanceFetchDevel') is called conditionally when devel: true. It also uses packages from devDependencies. As such, deployment to production is not supported.

Contributing

Pull Requests welcome! Please read CONTRIBUTING.md to avoid friction :) Mostly importantly, PRs should be submitted against the devel branch (our default branch) and commit messages should follow the conventionalcommits standard (basically Angular). This is important as we use semantic-release to automate releases and CHANGELOG entries when we merge back to master.
