This should shave down bundle sizes by 14.4 kb for many non-blaze projects.
The other core meteor packages have not depended on `underscore` since #9362. However, we are only able to remove this last dependency now due to the previous commit, which eliminated usages of `underscore` from apps that did not have the package listed in their `packages` files. This was causing CI test failures that now should be corrected.
Any meteor apps currently using `_` without `underscore` listed in their `packages` file will need to add the package explicitly.
Version number of `meteor-base` bumped from 1.3.0 to 1.4.0.
There are only a few uses of `underscore` in these apps, and two of them actually used `underscore` without having it explicitly listed in their `packages` file.
This is a problem, because the apps were relying on the dependency from `meteor-base`, which we want to remove to cut down bundle sizes.
For the `modules` test app, I've added `underscore` to the `packages` file, because it is using `_` in an assertion about the module system. For the other app and all other uses of `_`, rather than add `underscore` to the `packages` files, I took the modernization route and replaced the functions with their ES6 equivalents, and then removed `underscore` from all `packages` files.
mongo now transitively uses webapp (because ddp-server does) so we can't
really make an app with mongo and no webapp. This is a bit of a shame
and when we refactor the mongo package we should fix this... but until
then, let's just remove the no-longer-necessary main function and be OK
with this test running a pointless web server.
Specifically, Mongo.Collection objects on the server now have
rawCollection and rawDatabase methods.
You can use MongoInternals.NpmModules.mongodb.version to tell what
version of the mongodb npm module is the backend for HTTP.call. This
version may change incompatibly from version to version of Meteor; use
at your own risk. (For example, we expect to upgrade from the 1.4.x
series to the 2.x series in the not-too-distant future.)
Fixes#3640.
