EOSJS what is the keyProvider

Question

The Github Page of EOSjs mention a keyProvider to instantiate EOSjs. What is this? my private key?

Answer 1

Yes you need a private key. If you are doing a front-end where you need to use EOSjs and need user's private key, ask them to enable Scatter wallet instead and you simply get an eosjs object from Scatter instead.

Answer 2

Exactly, it provides private keys used to sign transactions.

Here the definition from the eosjs github page:

keyProvider [array|string|function]: Provides private keys used to sign transactions. If multiple private keys are found, the API get_required_keys is called to discover which signing keys to use. If a function is provided, this function is called for each transaction.

You just need to add it as the following (even if this is a fake private key):

keyProvider: ['5LLKiY1D3tCndrF5NW5tJa1enukCfrPNopUJwnkUmfErT8d11eN']
