It is throwing a Typescript error TS1254 when using @sinclair/typebox

[mf-karim]

I am trying to use dts-bundle-generator to create prebuilt files for my tool, namely index.js and index.d.ts. The main index.ts contains references to Type definitions which are defined using @sinclair/typebox. The index.js output file gets created successfully but the index.d.ts gives the following error error TS1254: A 'const' initializer in an ambient context must be a string or numeric literal or literal enum reference.

Do you have a repo? Is it the only log message the tool generates?

[mf-karim]

It's for a work related repo. But I can give you a gist. Basically I have a Type definition using sinclair and I am using that type definition in the index.ts. So when I try to generate the prebuilt files using dts-bundle-generator it regenerates the type in the output file (index.d.ts) as a const and I see the output error TS1254: A 'const' initializer in an ambient context must be a string or numeric literal or literal enum reference. Basically this error message and Error: Command failed

A minimal repro would be appreciated. Without it it would be hard to investigate the failure.

it regenerates the type in the output file (index.d.ts) as a const

Is it possible to share the line to code that it fails at? You can provide a --no-check flag to write output to the disk so you can analyse it later.

Basically this error message and Error: Command failed

Can you provide the full output? I understand that you don't want to share any private data (and I really don't need it), but I doubt the output contains anything private, and even if it does you can redact just that data without "rephrasing what you see".

The reasons why I'm asking the full log are:

• you didn't share any reproduction steps that I can replicate locally, so I need at least some information that I can use to help you with the issue you've faced
• while it might not look informative to you, in some circumstances I can see some hints that might help. E.g. it might be the compilation fails, not bundling itself (the bundling is a complicated process with multiple steps)

[mf-karim]

Basically my script runs this

execSync(
    `yarn dts-bundle-generator ${src} --out-file ${replaceFileExtension(
      out,
      '.d.ts',
    )} --silent --no-banner`,
    {
      stdio: 'inherit',
    },
  )

  $ node_modules/.bin/dts-bundle-generator src/index.ts --out-file prebuilt/index.d.ts --silent --no-banner
prebuilt/index.d.ts(3,30): error TS1254: A 'const' initializer in an ambient context must be a string or numeric literal or literal enum reference.
prebuilt/index.d.ts(12,30): error TS1254: A 'const' initializer in an ambient context must be a string or numeric literal or literal enum reference.

Do you have any updates on the minimal repro?

[timocov]

@mf-karim can you provide index.ts content? I just tried to use build a bundle with @sinclair/typebox library and I didn't see any issues. It looks like it is related to your code rather than a library you mentioned.

I'm going to close the issue. If you'll have any question or updates - feel free to ping me.
