Currently, Fauxton only shows the "latest" document's revision and there is no option to navigate through document revisions history.
As per CouchDB team - https://github.com/apache/couchdb-fauxton/issues/1069
Prior "revisions" exist only as a means to an end - consistent
replication. Compaction (and the automatic compaction daemon) or
replication can remove them at any time.
You can get additional information about the revisions for a given document by supplying the _revs_info argument to the query:
curl -X GET http://<HOST>:<PORT>/<DATABASE>/<DOC_ID>?revs_info=true
"_revs_info":[
{
"rev":"3-427991477c64de15dec603992bf4904a",
"status":"available"
},
{
"rev":"2-4cf070a1cb53ea5bf9554d665c8ba3e8",
"status":"available"
},
{
"rev":"1-2cee5b1e853387851535d34d0f056fb2",
"status":"missing"
} ]
Now you can access the previous version of the document revisions via CouchDB HTTP API:
curl -X GET http://<HOST>:<PORT>/<DATABASE>/<DOC_ID>?rev=2-4cf070a1cb53ea5bf9554d665c8ba3e8
