import isEqual from 'lodash.isequal'
to avoid loading the whole lodash module.
Please run yarn add -P lodash.isequal
to update package.json and yarn.lock as peerDependencies.
Hi @BlazPocrnja , would you mind adding a unit test for this behavior? |
@supasate I added unit tests and changed the lodash function to isEqualWith to allow for custom comparator functions as per this comment #394 (comment). |

Can you split this into another test? So, we have one for testing that it doesn't update if the location state structure doesn't change, and another one for testing that it updates if the location state structure changes.

No need to add a === undefined
which we doesn't test it. Only the second comparison is enough to test this comparison feature.

Looks good to me. Please rebase and fix some nits.
…ion test + spacing
@supasate Sorry for the delay! I made the changes you requested. Except when testing the custom state comparator function, there needs to be a check when the states are undefined (which is the case when you first push to history, or the store). I rewrote the test to make it a bit clearer. It's rebased now too! |
LGTM. Thanks for your contribution @BlazPocrnja ! |
I just noticed that it breaks the test because lodash.isequalwith is not listed in devDependencies. (https://travis-ci.org/github/supasate/connected-react-router/builds/665324580?utm_medium=notification&utm_source=github_status). I'm not sure why Travis didn't show up here. I'm fixing in #408. |
My apologies! Looks like it's passing now, so that's a relief. Thanks! |
Closes #394. This change deep compares location state objects to prevent incorrectly pushing to history multiple times when state is changed.
