eslint-plugin-webassembly

ESLint plugin for WebAssembly

Installation

You'll first need to install ESLint:

$ yarn add eslint --save-dev

Next, install eslint-plugin-webassembly:

$ yarn add eslint-plugin-webassembly --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-webassembly globally.

Usage

Add webassembly to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "webassembly"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "webassembly/no-unknown-export": 2
    }
}

Supported Rules

no-unknown-export

Checks that the exports exists, example:

Good:

import("module.wasm").then(x => {
  x.test();
});

import("module.wasm").then(({test}) => {
  test();
});

Bad:

import("module.wasm").then(x => {
  x.unknownExport();
});

import("module.wasm").then(({unknownExport}) => {
  unknownExport();
});

Parsing error: The keyword 'import' is reserved

ESLint doesn't support dynamic import out of the box. Make sure to check out https://github.com/babel/babel-eslint.
