eslint-plugin-require-explicit-generics

Allow configured functions to require explicit generics.

Why?

Some libraries are over-permissive with their types, allowing generics to be omitted defaulting them to the any type.
To prevent accidentally relying on this behaviour:
this plugin allows you to specify a list of functions and constructors that MUST have explicit generics set.

Example

If you list myFunction in your .eslintrc.js:
``ts
myFunction(); // ❌ ESLint: Function 'myFunction' must be called with explicit generics...
myFunction(); // ✅ ESLint: Pass
`

Installation

First install ESLint:
`shell

npm

npm install eslint --save-dev

yarn

yarn add eslint --dev
`
Next, install eslint-plugin-require-explicit-generics
`shell

npm

npm install eslint-plugin-require-explicit-generics --save-dev

yarn

yarn add eslint-plugin-require-explicit-generics --dev
`

Configuration (REQUIRED)

In your .estlintrc.js add "require-explicit-generics" to the plugin list.
`js
plugins: [
"require-explicit-generics",
],
`
Then in the rules section set "require-explicit-generics/require-explicit-generics"
pass the log level (either "error" or "warning"),
then the list of functions to check.
`js
rules: {
"require-explicit-generics/require-explicit-generics": [
"error",
// List your functions here
[ "myFunction", "myVar.myOtherFunction" ]
]
},
`
You can also use a map to define how many generics to expect for each function.
`js
rules: {
"require-explicit-generics/require-explicit-generics": [
"error",
{ "myFunction": 3, "myVar.myOtherFunction": 1 }
]
},
`
`ts
myVar.myOtherFunction(); // Function 'myVar.myOtherFunction' must be called with generics...
myFunction(); // Function 'myOtherFunction' called with too few explicit generics...
