Compatibility

Nuxt Kit utilities can be used in Nuxt 3, Nuxt 2 with Bridge and even Nuxt 2 without Bridge. To make sure your module is compatible with all versions, you can use the checkNuxtCompatibility, assertNuxtCompatibility and hasNuxtCompatibility functions. They will check if the current Nuxt version meets the constraints you provide. Also you can use isNuxt2, isNuxt3 and getNuxtVersion functions for more granular checks.

checkNuxtCompatibility

Checks if constraints are met for the current Nuxt version. If not, returns an array of messages. Nuxt 2 version also checks for bridge support.

Type

async function checkNuxtCompatibility(  constraints: NuxtCompatibility,  nuxt?: Nuxt): Promise<NuxtCompatibilityIssues>;interface NuxtCompatibility {  nuxt?: string;  bridge?: boolean;}interface NuxtCompatibilityIssue {  name: string;  message: string;}interface NuxtCompatibilityIssues extends Array<NuxtCompatibilityIssue> {  toString(): string;}

Parameters

constraints

Type: NuxtCompatibility

Default: {}

Constraints to check for. It accepts the following properties:

• nuxt (optional)
  Type: string
  Nuxt version in semver format. Versions may be defined in Node.js way, for exmaple: >=2.15.0 <3.0.0.
• bridge (optional)
  Type: boolean
  If set to true, it will check if the current Nuxt version supports bridge.

nuxt

Type: Nuxt

Default: useNuxt()

Nuxt instance. If not provided, it will be retrieved from the context via useNuxt() call.

assertNuxtCompatibility

Asserts that constraints are met for the current Nuxt version. If not, throws an error with the list of issues as string.

Type

async function assertNuxtCompatibility(  constraints: NuxtCompatibility,  nuxt?: Nuxt): Promise<true>;interface NuxtCompatibility {  nuxt?: string;  bridge?: boolean;}

Parameters

constraints

Type: NuxtCompatibility

Default: {}

Constraints to check for. It accepts the following properties:

• nuxt (optional)
  Type: string
  Nuxt version in semver format. Versions may be defined in Node.js way, for exmaple: >=2.15.0 <3.0.0.
• bridge (optional)
  Type: boolean
  If set to true, it will check if the current Nuxt version supports bridge.

nuxt

Type: Nuxt

Default: useNuxt()

Nuxt instance. If not provided, it will be retrieved from the context via useNuxt() call.

hasNuxtCompatibility

Checks if constraints are met for the current Nuxt version. Return true if all constraints are met, otherwise returns false. Nuxt 2 version also checks for bridge support.

Type

async function hasNuxtCompatibility(  constraints: NuxtCompatibility,  nuxt?: Nuxt): Promise<boolean>;interface NuxtCompatibility {  nuxt?: string;  bridge?: boolean;}

Parameters
