Recreate index from GET mappings output

I'm trying to find a way to recreate all index mappings from when I use GET /_all/_mapping or iterate over each index.
For creating development cluster purposes.
I have tried to use the json I get from get all mappings with Elasticsearch nodejs client, but putting the mappings object into client.index with specifying index name and mappings object as a mappings.

But it still didn't worked out as expected.

Is there a better way to "backup" mappings of indexes and recreating them ?
