Refactor to use javascript by edmundmiller · Pull Request #28 · seqeralabs/action-tower-launch

edmundmiller · 2025-08-08T15:13:53Z

I've been working on debugging AWS Megatests on nf-core, and I'm struggling to get a good error message.

I think part of this is because of the Russian nesting doll situation, with Docker and the tw cli to make the calls instead of just a JS package to call the API directly.

I'll try this in an nf-core pipeline first and see how it works, but it should also be backwards compatible(but we can cut a v3 release)

It works!(And fails properly)

Prevent CI from attempting to launch pipelines on release events when secrets may not be configured. The job will still run on pushes to dev/main branches and pull requests. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Set if: false to skip the Tower CI job entirely since secrets are not configured. Can be re-enabled later by changing to appropriate condition. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

We need to remove all the LLM-generated crud, but I'm sure maintaining it as JS or TS will be much easier.

- Remove unnecessary documentation files (API_COMPARISON.md, JAVASCRIPT_ACTION_SUMMARY.md, MIGRATION.md) - Delete legacy Docker scripts (entrypoint-api.sh, entrypoint.sh) that bypass JavaScript implementation - Simplify CHANGELOG.md to focus on key user-facing changes - Update README.md to remove implementation references and fix version - Add Development section with essential contributor information - Remove CLAUDE.md after integrating useful content 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Adam Talbot <12817534+adamrtalbot@users.noreply.github.com>

edmundmiller · 2025-08-13T19:49:47Z

@adamrtalbot I've got another PR waiting for a TypeScript migration.

I'm thinking

Refactor to use javascript #28
Remove Tower Mentions #30
Typescript Migration
Release v3.

Shouldn't break anything for nf-core because the pipelines are locked into v2.

It's stale

ewels

Really nice!

Main overarching comment is whether we can get rid of debug and always print lots of debugging info. Then group log messages so that it's still clean and easily Human-readable.

Other than the main thing is the invalid watch URLs, and a few minor suggestions.

This is really nice stuff, great work! 🙌🏻

+        workflowData.workflowId,
+        inputs.workspaceId,
+        {
+          maxWaitTime: 30 * 60 * 1000, // 30 minutes


Can we not go longer than this?

An action step can go for 6 hours

ewels · 2025-08-20T08:31:25Z

Did you just write your own API SDK again?

We need a better openAPI spec so it's trivial to write an SDK.

Or a public JS / TS SDK which can just be imported from npm...

adamrtalbot · 2025-08-20T09:39:29Z

+    # Disabled - secrets not configured
+    if: false


if: false?

What's this for? Can we just remove it?

adamrtalbot · 2025-08-20T09:59:21Z

+      // Construct URL if not provided by API
+      const baseUrl = inputs.apiEndpoint.replace('/api.', '/').replace('/api', '');
+      if (inputs.workspaceId) {
+        workflowUrl = `${baseUrl}/orgs/-/workspaces/${inputs.workspaceId}/watch/${workflowData.workflowId}`;


The API uses workspace as a parameter (?workspaceId=<integer>), is that not the case here?

adamrtalbot · 2025-08-20T10:01:19Z

+      // Mask sensitive values
+      if (key.includes('Id') && value) {

Yep the URL to the workflow will be masked.

+    if (error.stack && isDebug) {

+    }


Is this needed?

+          success: false,
+          error: error.message,
+          timestamp: new Date().toISOString(),
+          stack: error.stack
+        };
+
+        try {
+          fs.writeFileSync(jsonFile, JSON.stringify(errorOutput, null, 2));
+          logMessage(logFile, `Error JSON output written to: ${jsonFile}`);
+        } catch (writeError) {
+          logMessage(logFile, `Failed to write error JSON file: ${writeError.message}`, 'ERROR');
+        }
+      }
+    }


I think there are easier ways of handling this then one massive try/catch

…wer-launch into refactor-javascript

Looks like probably addressed

- Remove require.main guard (node20 actions require() the file, never runs as main) - Fix workflow status parsing: API nests under workflow.status not data.status - Fix personal workspace URL: fetch /user-info for /user/{name}/watch/{id} - Fix typo: TipL -> Tip: - Fix log timestamp: .slice(0,10) only gave date, now includes time - Increase wait timeout from 30min to 6hr (GH Actions step limit) - Harden access token validation for empty strings - Fix labels format: API expects {name} objects via labelIds field - Add getUserInfo method for URL construction - Rebuild dist

ewels · 2026-08-18T19:23:19Z

@edmundmiller I'm now thinking that (a) this is a nice change but (b) let's just write a totally new action which is called seqera-platform-launch, instead of messing with a rewrite on this one.

Cleaner break, and makes it easier to dev + test before switching somehow (yes I know we could do that with versions but this feels safer).

What do you think?

edmundmiller · 2026-08-18T19:29:35Z

Agreed, let's do it!
