QUESTION
I am rather confused as I have read that top level await is supported in ESM but when I try it out in a html file it does not work?
Were I found that is says: Top-level await does not work with node 14.13.- "Top-level await only works with ESM modules"
Is top level await supported in ESM and if how can I use it.
...ANSWER
Answered 2022-Jan-20 at 18:34Yes, it's supported in ESM - ES6 modules. It's not supported in plain script tags.

With top-level await accepted into ES2022, I wonder if it is save to assume that await import("./path/to/module") has no timeout at all.
Here is what I’d like to do:
ANSWER
Answered 2021-Aug-07 at 17:46As far as I know, there is no timeout by default in async-await. There is the await-timeout package, for example, that is adding a timeout behavior. Example:

Hi I've been trying to create a checkout session using the stripe firebase extension and I ran across this error:
./pages/viewer.js Module parse failed: The top-level-await experiment is not enabled (set experiments.topLevelAwait: true to enabled it) File was processed with these loaders:
- ./node_modules/next/dist/build/babel/loader/index.js You may need an additional loader to handle the result of these loaders. Error: The top-level-await experiment is not enabled (set experiments.topLevelAwait: true to enabled it)
I'm not sure what the error is referring to. It's a whole new concept to me.
I'm using the next.js framework

QUESTION
I have node 14.13.0, and even with --harmony-top-level-await, top level await is not working.
...ANSWER
Answered 2020-Nov-26 at 08:11Top-level await only works with ESM modules (JavaScript's own module format), not with Node.js's default CommonJS modules. From your stack trace, you're using CommonJS modules.
You need to put "type": "module" in package.json or use .mjs as the file extension (I recommend using the setting).
For instance, with this package.json:

So im trying to do an async call with redux thunk in webpack but get a weird message - 'await' is only allowed within async functions and at the top levels of modules

Answered 2020-Nov-16 at 22:04i think there's an issue with how you declared your function, this is what you have:
QUESTION
Top level await support was added to Node.js in 14.3.0 via --experimental-top-level-await and later to --harmony-top-level-await.
I need to use a top level await in my ESM script file, if it is supported by the current Node.js runtime. And further, I need to set a boolean flag to indicate that the promise was successfully awaited at the top level.
An example of what I mean:
...ANSWER
Answered 2020-Nov-03 at 21:08Seems like you might be able to check the version of node being used at runtime like so process.version and then you can use also use process.argv to check for any flags passed in when starting the process.
Using the above methods, you can first check the version of node being used, and then if relevant, you can check for the needed flags.
Node docs on checking for CLI args.
QUESTION
I am trying to run node 14 with my package.json set as module:
...ANSWER
Answered 2020-Sep-09 at 09:47If we take a look at the spec there's this section which states:
The current specifier resolution does not support all default behavior of the CommonJS loader. One of the behavior differences is automatic resolution of file extensions and the ability to import directories that have an index file.
There's another section which states:
A file extension must be provided when using the import keyword. Directory indexes (e.g. './startup/index.js') must also be fully specified.
So it seems that the extension is actually necessary. Howvever, there's the option --experimental-specifier-resolution which you try setting to --experimental-specifier-resolution=node.
