THREADS_WORKER_INIT_TIMEOUT environment variable

[lsavage92]

Hello again! 👋

As far as I can tellTHREADS_WORKER_INIT_TIMEOUT is an undocumented environment variable but I had to track it down due needing a longer timeout. Unfortunately in Vue applications we must specific our environment variables with a prefix of VUE_APP_. Because of this, I cannot increase the timeout of the worker init timeout without modifying the source of this library.

Is there anyway we can set which environment variable the library will look for?

Hey @lsavage92! Sorry, your question kind-of slipped my attention...

That’s a tricky one. In short: Right now you cannot, no.

I don’t know Vue too well. Is there maybe any way to opt-in to other env vars being processed when they don’t start with VUE_APP_?

I'm hesitant to check for another env var just for the Vue users. Does that concern every Vue app?

Hey thanks for responding! I think you are making the right move. I found recently that in the vue config file you can modify the environment like so:

module.exports = {
    chainWebpack: config => {
        
        const env = {
            // Notice the backticks AND the single quote. You need both.
            ENV_PROPERTY: `'ENV_VALUE'`,
            ENV_PROPERTY_2: `'${process.env.TEST}'` // Add value from existing env.
        }
        
        config.plugin('define')
            .tap(args => {
                Object.assign(args[0]['process.env'], env)
                return args
            })
    }
}

This should allow you to assign an env var from process.env to a namespace other than one prefixed with VUE_APP.

Sounds good! Can I close the issue already or do you want to try it first?

On a different, but related note: The THREADS_WORKER_INIT_TIMEOUT variable might also be worth documenting.

Yes please close the issue! I have already confirmed that the above solution works. But I agree! That configuration can be useful!
