Migrating from Underscore to Lodash
// By Matthew Gerstman and Stacey Sern • Sep 05, 2018 The core Dropbox web application is 10 years old and used by millions of users per day. Hundreds of front-end engineers across multiple cities actively work on it. Unsurprisingly, our codebase is very large and somewhat irregular. Recently written parts have thorough test coverage, other parts haven't been updated in years. Over the past two ye

Dropbox API v2 launches today | Dropbox Developer Blog
Today we're excited to launch Dropbox API v2! We announced a preview of API v2 in April, and have continued to update and improve the API based on your feedback. As of today, Dropbox API v2 is ready to be used in all your Dropbox-connected apps. Thank you to the hundreds of developers who have already tried out API v2 in preview. Our goal with API v2 is to provide a simpler, more consistent, and m
Open Sourcing Our Go Libraries
Dropbox owes a large share of its success to Python, a language that enabled us to iterate and develop quickly. However, as our infrastructure matures to support our ever growing user base, we started exploring ways to scale our systems in a more efficient manner. About a year ago, we decided to migrate our performance-critical backends from Python to Go to leverage better concurrency support and
Announcing Dropbox webhooks
I'm excited to announce Dropbox webhooks, a way for server-side apps to get real-time notifications about file changes in Dropbox. Client-side applications have already been able to get low-latency notifications via longpoll_delta or the built-in notifications in the Sync API. Webhooks give this same ability to server-side apps, eliminating the need for polling. In general, a webhook is a way for
Dropbox dives into CoffeeScript
// By Dan Wheeler , Ziga Mahkovec , and Chris Varenhorst • Sep 13, 2012 During July's Hackweek, the three of us rewrote Dropbox's full browser-side codebase to use CoffeeScript instead of JavaScript, and we've been really happy with how it's been going so far. This is a controversial subject, so we thought we'd start by explaining why. CoffeeScript: By the way, the JavaScript has a scoping bug, di
Introducing Pyston: an upcoming, JIT-based Python implementation
Introducing Pyston: an upcoming, JIT-based Python implementation Hello everyone, I’m very excited to announce Pyston, a new open-source implementation of Python, currently under development at Dropbox. The goal of the project is to produce a high-performance Python implementation that can push Python into domains dominated by traditional systems languages like C++. Here at Dropbox, we love Python
The Datastore API: a new way to store and sync app data
Hey developers, Today, we're excited for you try out the beta release of the Datastore API — simple databases for your apps with Dropbox sync built-in! Use datastores to save your app's data — settings, contacts, or any other content that users create — and Dropbox will take care of all the syncing for you. People who use your Datastore-enabled app can be sure their information will always be up-t
Welcome Guido!
Today we’re excited to welcome a new member of the Dropbox family under unusual circumstances. Though he's joining us now, his contributions to Dropbox date back to day one, all the way to the very first lines of code. Some people only need to be introduced by their first name, and the BDFL is one of them. Dropbox is thrilled to welcome Guido, the creator of the Python programming language and a l
The new /delta API call (beta)
From the very first release of the Dropbox API, developers have asked for ways to efficiently keep up with changes to files in Dropbox. Today we're releasing something that takes the API a step in that direction. The new /delta API call returns a list of delta entries that describe what has changed in a user's Dropbox, allowing the app to update its local state to match. The app stills need to pol
