eslint-plugin-goog

Usage

1) Install the package:

npm i eslint-plugin-goog --save-dev

2) Specify "goog" as a plugin in your .eslintrc:

{
    plugins: [
        "goog"
    ]
}

3) Enable all of the rules that you would like to use in your .eslintrc:

{
    rules: [
        "goog/no-undeclared-deps": ...
    ]
}

Rules

no-undeclared-deps (fixable)

Use this rule to detect usage of undeclared dependencies (missed goog.require(<namespace>) expression).

Options:

{
    domains: string[], // List of root namespaces that rule will use for report as undeclared
    excludedPatterns: string[], // List of patterns (string literally or RegExp pattern string) that will be excluded from reports
    knownNamespaces: string[] // List of provided namespaces that rule will be able to fix
}

Also domains and knownNamespaces can be specified by shared settings.

Caveat: only namespaces that are given by options knownNamespaces will be auto fixed. Plugin provides module nsUtils to ease retrieving of known namespaces, e.x.:

// Your .eslintrc.js

const {nsUtils} = require('eslint-plugin-goog');

const knownNamespaces = [
    ...nsUtils.findByPattern(path.join(__dirname , 'myapp', '**', '*.js')),
    ...nsUtils.findByPattern(path.join(__dirname , 'node_modules', 'zombiebox', '**', '*.js')),
];

module.exports = {
    // ...
    rules: [
        'goog/no-undeclared-deps': ['error', {
            domains: ['myapp'],
            knownNamespaces
        }]
    ]
}

no-unused-deps (fixable)

Use this rule to detect when declared dependencies (goog.require(<namespace>) expression) are unused in code.

Options:

{
    domains: string[] // List of root namespaces that rule will use for report as undeclared
}

Also domains can be specified by shared settings.

no-duplicates (fixable)

Use this rule to prevent duplicates in goog.require or goog.provide expressions.

right-order (fixable)

Use this rule to achieve right order of goog expressions. This rule does:

Checks that goog expressions are sorted alphabetically by its namespace;
Checks that goog expressions are at top of a file;
Checks that goog.provide goes before goog.require;
Checks that there are no additional code or comments between goog expressions;
Restricts nested goog expressions (parent AST node should have Program type).
