ESLint是否存在仅允许从指定模块导入特定命名导出的规则？

Great question! You're right that no-restricted-imports feels like it's built for "allow all except X" scenarios, but you can repurpose it to enforce a "deny all except X" pattern using regex magic. Here's how to set it up:

Step 1: Update your ESLint config #

Add this rule to your .eslintrc.json (or equivalent config file):

{
  "rules": {
    "no-restricted-imports": [
      "error",
      {
        "paths": [
          {
            "name": "@prisma/client",
            "importNames": ["/^(?!Prisma$|PrismaClient$).+/"],
            "message": "Only Prisma and PrismaClient may be imported from @prisma/client."
          }
        ]
      }
    ]
  }
}

How this works #

The regex /^(?!Prisma$|PrismaClient$).+/ uses a negative lookahead to match any import name that is not exactly Prisma or PrismaClient. Here's the breakdown:

• ^ and $ ensure we match the entire import name (no partial matches)
• (?!Prisma$|PrismaClient$) excludes the two allowed names
• .+ matches any other non-empty string

Example behavior #

• ✅ Valid: import { Prisma, PrismaClient } from '@prisma/client'; (no error)
• ❌ Invalid: import { Airline, Airport } from '@prisma/client'; (triggers error)
• ❌ Invalid: import { User } from '@prisma/client'; (triggers error)
• ❌ Invalid: import { Prisma, User } from '@prisma/client'; (triggers error because User is restricted)

Notes #

• This works in ESLint v6 and above, which supports regex patterns in importNames.
• If you need to allow additional imports later, just add them to the regex's negative lookahead. For example, to allow PrismaPromise:

  /^(?!Prisma$|PrismaClient$|PrismaPromise$).+/
