Hey super heroes! I want to write some of the stack outputs to a local JSON file (Similar to how the

StaticSite.environment

field writes to the

static-site-environment-output-values.json

) How would I do that? My specific use case is that I'm setting up DynamoDB Onetable, and I want to put the table name and function ARN into a config file for it so I don't need to manually grab them and paste.

Assuming you're in a JS/TS environment, you could just use fs.writeFile() and grab the various outputs you need. We pass an object to this.addOutputs(). You could JSON.stringify that same object and write it to disk

The problem is that the stack hasn't deployed at that time, so it just outputs tokens.

sst deploy

takes an

--outputs-file

parameter

Thanks @Gabriel Bleu! I missed that! Do you know if there is a way to "hard code" that?

Like adding it to the start script in

package.json

?

I guess I could... but then how to run a script afterwards to take the required info from the file and write the file I need? The

sst start

command doesn't terminate.

Oh yeah, of course

Just letting @Frank @thdxr know about the hooks idea.

Hey @Ryan

I want to put the table name and function ARN into a config file

Do you want to do this on

sst deploy

or

sst start

?

Hi @Frank, on sst start, or deploy. Either in this case.

cdk has the option save outputs to a file in json format using the --outputs-file flag

cdk deploy --outputs-file outputs.json

sst supports this flag https://docs.serverless-stack.com/packages/cli#options

I could make it work with that, if I ran that and then other commands by npm scripts. But it would probably save a few errors and frustrations in the future if there was a way to do it directly.
