Firebase-tools: Using firestore.indexes.json

[universse]

I can't seem to find the documentation for firestore.indexes.json. I want to remove certain single-field index with it rather than using the console.

Take a look here: https://github.com/firebase/firebase-tools/issues/1127

What you're asking currently doesn't work - firestore.indexes.json just appends, but never removes.

Thanks for jumping in @LFDM.

@universse as stated above, right now the indexes file is "append only" and never deletes an index. However I think what you want to do is possible, since removing an index on a single field is done by adding an empty index configuration.

So let's say you want no indexes on myfield in the mycollection collection:

firestore.indexes.json

{
  indexes: [],
  fieldOverrides: [
    collectionGroup: "mycollection",
    fieldPath: "myfield",
    indexes: []
  ]
}

Hope that helps!
