Ancillary Packages
|
|
------------------
|
|
|
|
These are a number of packages not included in the umbrella `ethers` npm package, and
|
|
additional packages are always being added. Often these packages are for specific
|
|
use-cases, so rather than adding them to the umbrella package, they are added as
|
|
ancillary packaged, which can be included by those who need them, while not bloating
|
|
everyone else with packages they do not need.
|
|
|
|
We will keep a list of useful packages here.
