Upgrading
This page lists the breaking API changes between major versions of Kinto.js, as well as upgrade tips.
4.x to 5.x
- The helper
utils/reduceRecords
was removed (#543) collection.sync()
now rejects asynchronously when the specified remote is invalid (#540)incoming-changes
hook now receives decoded records- Remote deletion conflicts are now resolved with decoded records
- Last pull step in sync() only retrieves what was changed remotely while pushing local changes
importChanges()
method was changed and now accepts a list of records and a strategy stringpushChanges()
method was changed and now accepts a list of records- the database is not scanned anymore when pushing conflicts resolutions
3.x to 4.x
- Deleted records are now decoded/encoded (#510)
2.x to 3.x
cleanRecord()
The cleanRecord()
function from the collection module was dropped. Since local fields can be defined at the collection level, a cleanLocalFields()
method was introduced instead.
SyncResultObject
The format of updates and deletions in the SyncResultObject
has changed.
- The
updated
list now contains a list of objects withold
andnew
attributes - The
deleted
list now contains the full old record instead of just a stripped object containingid
Before with 2.X:

lastModified: 1434270764485,
conflicts: [],
errors: [],
created: [],
updated: [{
id: "08d5ae32-7f73-46bb-a8a6-c2bd80b15705",
title: "blog post",
_status: "synced",
last_modified: 1434270764485

published: [],
resolved: [],
deleted: [{
id: "131a100d-0732-494e-aa3c-e4a15e23eb77"
}],
}
Now with 3.X:
{

}],
}
1.x to 2.x
Kinto.js 2.x introduces general usage of transactions in database adapters. This change doesn't impact the Collection
API, so most users shouldn't be impacted by this change.
As localStorage doesn't support transactions, its support has been entirely dropped. If you were using it in a Kinto.js 1.x project, please switch to using the default IndexedDB one when upgrading to Kinto.js 2.x.
The BaseAdapter
interface has been updated to reflect the now mandatory reliance on transactions:
- The
Adapter#create()
,#update()
and#delete()
methods are now gone; - The
Adapter#execute()
method is now to be used whenever you want to write to the database.
Any code directly invoking adapter methods should be updated to reflect this change, by calling #execute()
instead of atomic operations; so instead of writing:
db.create({id: 1, title: "foo"})
.then(_ => db.create({id: 2, title: "bar"}));
You now need to write:
db.execute(transaction => {
transaction.create({id: 1, title: "foo"});
transaction.create({id: 2, title: "bar"});
})
Note
Once again, you usually don't have to worry about this change if you're only relying on the
Collection
public API, whereCollection#create()
and friends are still available.
