Revision history

Every time you change a collection or an item, a new revision is created in Etebase. Each revision is a snapshot of the collection or item at that point in time so you can easily view and rollback changes.

This is very useful if you would like to offer a change history to your users, or even if you just want to make sure your data is never lost, even if you make a mistake.

Listing revisions

Listing revisions returns normal items you can then manipulate like any others. The items are sorted newest to oldest.

const item = await itemManager.create(
{ type: "file", },
"First draft",
await itemManager.batch([item]);

item.setContent("Second draft");
await itemManager.batch([item]);

const revisions = await itemManager.itemRevisions(item);
assert( === 2);

// Revisions are normal items so we can use them as such
const content = await[1].getContent();
assert(content === "First draft");

// Collections are just items, so for collection revisions:
const collectionRevisions = await itemManager.itemRevisions(collection.item);

Iterating through revisions

Like the rest of the API, revisions can be iterated over.

let iterator = null;
while (true) {
const revisions = await itemManager.itemRevisions(item, { iterator, limit: 5 });
iterator = revisions.iterator;


if (revisions.done) {
