You can use yarn resolutions or npm overrides to force a version of ts-node that supports a more recent typescript version

This came up in our issue tracker before:
• <https://github.com/pulumi/pulumi/pull/10122>
• <https://github.com/pulumi/pulumi/issues/8177>

Status so far: this will be work for Pulumi v4, given Typescript v4 has breaking changes.

<@U02RY3FTY9L> Just use Javascript &amp; everything is solved :smile:

(but srsly - I don’t like TS because it bloats `node_modules`, *slows down work* because of the *transpilation* step, makes *upgrades harder* (you have to upgrade all TS dependencies), *bloats Lambda functions* etc. etc.)

(I know that one of the Pulumi founders worked on TS, so that’s why Pulumi is forcing it, but sorry I just don’t find it that useful, if I want a strong/static typing system I’ll just use Go)

FYI, we aren’t forcing you to use Typescript. You can use any of our NPM packages without TypeScript at all.

There are a number of Javascript only examples here: <https://github.com/pulumi/examples>
Search for `-js-` in the top level folder name.

<@UK4HNFLCB> sorry, wrong word, not `forcing` -&gt; `coercing` :smile: (or some more softer word, sry English is not my native lang.)

coercing is still too strong of a word. They encourage TS but you have 100% freedom to use JS. There's no loss in features/support.

Not all type systems are created equal though. Go's is (intentionally) very limited and not at all comparable to TS.

Then there is Go, Java, dotnet, python SDKs as well

<@U0444JWUNLU> Yup, but I feel that vanilla Javascript/Node.js goes best with Pulumi, it’s very lightweight, flexible and expressive :slightly_smiling_face:

On one of our biggest projects we properly set up the Pulumi projects with JS, and the Ops people loved it, as well as the Developers - it was awesome. (not to mention that we could write AWSLambdas (almost) seamlessly in the same codebase &amp; they were extremely lightweight (&lt;1kb most of the time). It was glorious :)
