The ern add <packages..>
command is the ern
equivalent of yarn add
and npm install
When you work with a MiniApp, always use ern add
to add packages in place of yarn add
or npm install
.
The ern add <packages..>
command runs yarn add
and it performs important additional compatibility checks.
You don't need to specify an explicit version for a package that you add using ern add
. If you add an explicit version for a package, it is ignored.
If the package is declared in the current platform manifest, then the version from the manifest is used.
The ern add <packages>
command performs the following checks:
If the package is declared in the manifest, then ern
installs the package at the version declared in the manifest.
If the package is not declared in the manifest, then additional checks are performed:
If the package contains native code in any way (the package itself is a native module or it transitively contains one or more native dependencies, the command denies the package installation until a configuration is added to the manifest for this package.
If the package contains only JavaScript code, then the command proceeds with the package installation without further checks.
