I've created a module to verify if all the necessary environment variables are properly set in a React application. Here's a simple example of how it works:
const getEnvironmentVariable = (key: string): string => {
if (process.env[key]) {
return process.env[key] as string;
}
throw new Error(`Missing mandatory environment variable ${key}`);
}
type Config = {
foo: string
}
const config: Config = {
foo: getEnvironmentVariable('REACT_APP_FOO')
}
export default config;
This code is effective during app execution, but it would be beneficial to also run it in CI to identify missing variables before deployment :)
However, when attempting to run it using ts-node, an error occurs:
ts-node src/config/environmentVariables.ts
(node:30355) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
(...)/src/config/environmentVariables.ts:38
export default config;
^^^^^^
SyntaxError: Unexpected token 'export'
Does anyone have suggestions on how to address this without resorting to tactics like temporary files?
Best regards, Julien
