This is an unofficial tRPC client devtools extension that you can use to inspect queries, mutations and subscriptions from your tRPC app!

In order to use it, you need to install the trpc-client-devtools-link npm package and add it to your tRPC client config (if you're using tRPC v10, install the @next version)

The tRPC Client Devtools appear as a "tRPC" tab in your Firefox inspector when tRPC is detected, alongside other tabs like "Elements" and "Console". The devtools currently have 3 main features:

- Query inspector: View the input, result and elapsed time of the fired queries.
- Mutation inspector: View the input, result and elapsed time of the fired mutations.
- Subscription inspector: View the input, multiple results and their elapsed time of the subscriptions.

Risk impact

tRPC Client Devtools requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install tRPC Client Devtools if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

tRPC Client Devtools is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on, especially ones with higher risk impact and/or higher risk likelihood.
