The DownThemAll! WebExtension.
For those still on supported browser: Non-WebExtension legacy code.
This is the WebExtension version of DownThemAll!, a complete re-development from scratch. Being a WebExtension it lacks a ton of features the original DownThemAll! had. Sorry, but there is no way around it since Mozilla decided to adopt WebExtensions as the only extension type and WebExtensions are extremely limited in what they can do.
For what is planned (and not planned because impossible to do in WebExtensions), see TODO.md.
What this furthermore means is that some bugs we fixed in the original DownThemAll! are back, as we cannot do our own downloads any longer but have to go through the browser download manager always, which is notoriously bad at handling certain "quirks" real web servers in the wild show. It doesn't even handle regular 404 errors.
I spent countless hours evaluating various workarounds to enable us to do our own downloads instead of relying on the downloads API (the browser built-in downloader). From using IndexedDB to store retrieved chunks via XHR, to doing nasty service-worker tricks to fake a download that the backend would retrieve with XHR. The last one looks promising but I have yet to get it to work in a manner that is reliable, performs well enough and doesn't eat all the system memory for breakfast. Maybe in the future...
What this also means is that we have to write our user interface in HTML, which never looks "native" and cannot offer deep OS integration.
But it is what it is...
What we can do and did do is bring the mass selection, organizing (renaming masks, etc) and queueing tools of DownThemAll! over to the WebExtension, so you can easily queue up hundreds or thousands files at once without the downloads going up in flames because the browser tried to download them all at once.

You will want to run yarn to install the development dependencies such as webpack first.
Just use your favorite text editor to edit the files.
You will want to run yarn watch.
This will run the webpack bundler in watch mode, transpiling the TypeScript to Javascript and updating bundles as you change the source.
Please note: You have to run yarn watch or yarn build (at least once) as it builds the actual script bundles.
I recommend you install the web-ext tools from mozilla. It is not listed as a dependency by design at it causes problems with dependency resolution in yarn right now if installed in the same location as the rest of the dependencies.
If you did, then running yarn webext (additionally to yarn watch) will run the WebExtension in a development profile. This will use the directory ../dtalite.p to keep a development profile. You might need to create this directory before you use this command. Furthermore yarn webext will watch for changes to the sources and automatically reload the extension.
Alternatively, you can also yarn build, which then builds an unsigned zip that you can then install permanently in a browser that does not enforce signing (i.e. Nightly or the Unbranded Firefox with the right about:config preferences).
You have to build the bundles first, of course.
Then put your Chrome into Developement Mode on the Extensions page, and Load Unpacked the directory of your downthemall clone.
To get a basic unofficial set of zips for Firefox and chrome, run yarn build.
If you want to generate release builds like the ones that are eventually released in the extension stores, use python3 util/build.py --mode=release.
The output is located in web-ext-artifacts.
-fx.zipare Firefox builds-crx.zipare Chrome/Chromium builds-opr.zipare Opera builds (essentially like the Chrome one, but without sounds)
- Install the requirements.
yarn && python3 util/build.py --mode=release- Have a look in

Before submitting patches, please make sure you run eslint (if this isn't done automatically in your text editor/IDE), and eslint does not report any open issues. Code contributions should favor typescript code over javascript code. External dependencies that would ship with the final product (including all npm/yarn packages) should be kept to a bare minimum and need justification.
Please submit your patches as Pull Requests, and rebase your commits onto the current master before submitting.
The code base is comparatively large for a WebExtension, with over 11K sloc of typescript. It isn't as well organized as it should be in some places; hope you don't mind.
