# General Translation Integrations: Supported file formats
URL: https://generaltranslation.com/en-GB/docs/integrations/paraglide/reference/file-formats.mdx
Docs index: https://generaltranslation.com/llms.txt
Description: The component formats analysed for Paraglide JS message usages and the tools each one needs. Reference for supported file formats.

JavaScript, TypeScript, and JSX files are parsed directly, including Lit-style `` html`…` `` templates. Every other format is converted to TypeScript by the framework's own tooling, which is loaded from your app so its version matches the framework's.

## Formats [#formats]

Those tools are not bundled. Install the ones for the formats your app uses:

| Files                                                                     | Needs in the app                                                                                                         |

| `.svelte`                                                                 | `svelte2tsx` (comes with `svelte-check`) and `svelte`                                                                    |

| Angular `.ts` and `.html`, `.ag`, `.analog`                               | `@angular/compiler`                                                                                                      |

| `.gjs`, `.gts`                                                            | `@glint/ember-tsc`                                                                                                       |

## Missing tools [#missing-tools]

* A format whose tool is not installed is skipped with one warning which names what to install.
* A tool is found when it is a dependency of the app or of one of the app's dependencies, so `svelte-check` is enough for `.svelte` files.
* The Vue and MDX tools need a `typescript` version with a JavaScript API: 5 or 6.
* A file that its tool rejects is skipped with a warning. The rest of the format is still analysed.

## Other formats [#other-formats]

Each built-in format is a language passed to the [`languages`](/docs/integrations/paraglide/reference/collect-context#languages) option. To analyse a format that is not listed, write your own. (See [Adding file formats](/docs/integrations/paraglide/guides/adding-file-formats)).
