Static import only works in an ECMAScript Module context. The script type must be module in the browser; in Node.js, the file extension, the nearest package.json file's type field, and the used runtime version must be consistent.
SyntaxError: Cannot use import statement outside a module
Warning: To load an ES module, set "type": "module"
import declarations may only appear at top level of a moduleStatic import only works in an ECMAScript Module context. The script type must be module in the browser; in Node.js, the file extension, the nearest package.json file's type field, and the used runtime version must be consistent.
A SyntaxError may stop all subsequent scripts; First resolve the first red record in the Console.
Determine whether the error is source or build with Source map, pretty print and Network URL.
Reduce the issue to a small area with node --check, ESLint, TypeScript or JSON validator.
Check the PHP render, API body, CDN cache and module loader result in the production answer.
Do not mix import and require randomly in the same file.
Meaning: File is being parsed as CommonJS or classic script.
Possible cause: type module, .mjs or script type missing.
Meaning: The browser does not recognize the script as a module.
Possible cause: type=module eksik.
Meaning: Node .js file accepts CommonJS.
Possible cause: package.json type field is missing.
Meaning: The CommonJS API is being used in an ESM file.
Possible cause: Mixed module sistemi.
Meaning: ESM’de CommonJS globali yok.
Possible cause: Module system changed.
Meaning: Node TypeScript source file is executed directly.
Possible cause: Loader/derleme yok.
Meaning: Test runner ESM/transform configuration is missing.
Possible cause: Babel/ts-jest setting.
Meaning: Static import used in a block/function.
Possible cause: Incorrect location.

node -vDisplays the running Node.js version.
node -e "const p=require('./package.json'); console.log(p.type,p.main,p.module)"package.json shows module fields.
node --check src/app.jsTests if the file is parsed in the current module's comment.
node -e "const fs=require('fs'),p=require('path'); let d=process.cwd(); while(true){const f=p.join(d,'package.json'); if(fs.existsSync(f)){console.log(f);break} const n=p.dirname(d); if(n===d)break; d=n}"Finds the closest package.json location that the Node can be affected by.
npx tsc --showConfigShows the real tsconfig module, target and moduleResolution settings.

Node version, package.json module type, build output, and the actual file run should comply with the same module system.
PHP warnings, theme HTML, redirects, and double script loading JavaScript errors may appear.
It occurs when the JavaScript parser, JSON parser, or module loader cannot find the expected grammar.
The line is usually where the parser detects the error. Missing quotes, parentheses, or commas may be in the previous line.
Use source map and DevTools pretty print; correct the original source file and rebuild.
PHP warning, HTML error page or unpadded data pressed may break JavaScript/JSON syntax.
Most parsers find most errors; however, incorrect server response, double script loading, and runtime module configuration should also be checked.
Deploy, minify, cache, package update, Node version, PHP output or half-loaded file behavior may have changed.
Provides diagnostic and safe repair steps; changes should be tested in the staging environment and reverted using Git.
We examine Console, Fetch/AJAX, PHP JSON responses, ES Modules, TypeScript build and WISECP script loading problems without disrupting the production structure.
