Techmmunity - Style Guide
In this package, you can find the Techmmunity Style Guide. We try to keep a clean and consistent code style, with modern features and using best practices.
⚠️ WARNING ⚠️
This package may not be updated so often, but it not means that it has been abandoned. We do the config in a way to (almost) never have to touch it again, and we only update the package to add new features, what may don't need to happen so often.

Modules
Alert: After any change at eslintrc.json file, you must restart VSCode.
Alert: The common module must ALWAYS be extend, and must ALWAYS be the fist one.
This repository contains the best practices divided by libs, frameworks and tools. The currently existent modules are:
Common
The common module is the default rules used by every javascript project. It doesn't contains any special config for frameworks, backend, frontend or npm package. You must import this module if you want to use any of the other modules of this package.

}Combining Modules
You can safely combine some modules, like this:
{
"root": true,
"extends": [
"@techmmunity/eslint-config/common", // The common module always should be extended!
"@techmmunity/eslint-config/typescript",
"@techmmunity/eslint-config/jest"
]
}But in some cases, where that module is already imported, it will cause a conflict, like in this case:
{
"root": true,
"extends": [
"@techmmunity/eslint-config/common", // The common module always should be extended!
"@techmmunity/eslint-config/nextjs"
]
}Warnings
Problems with Prettier
If you are using the VSCode Prettier Extension, you need to disable it, because this package already configs the prettier and uses it under the hood.
To disable Prettier, you just need to add this to your vscode configs:
{
"[javascript]": {
"editor.defaultFormatter": null
},
"[typescript]": {
"editor.defaultFormatter": null
},
"[javascriptreact]": {
"editor.defaultFormatter": null
},
"[typescriptreact]": {
"editor.defaultFormatter": null
}
}You can access this configs by pressing Ctrl + Shift + P and tipping Preferences: Open Settings (JSON).
