Question 1

How to set up Ember Language Server in VSCode?

Accepted Answer

Install the 'Unstable Ember Language Server' extension from the VSCode marketplace. After installation, it should automatically detect Ember projects with classic structure and provide features like autocompletion and linting, but ensure your project has the required dependencies like ember-template-lint.

Question 2

Does Ember Language Server work with TypeScript in Ember.js?

Accepted Answer

Yes, ELS supports TypeScript files, offering autocompletion for Ember entities in .ts files and template linting in .gts files. It integrates with the Ember ecosystem to provide intelligent suggestions tailored to TypeScript usage in Ember projects.

Question 3

Ember Language Server vs generic JavaScript language server: which is better for Ember development?

Accepted Answer

ELS is superior for Ember.js because it provides deep framework integration, such as route autocompletion in link-to components and Ember-specific definitions, which generic servers lack. For non-Ember projects or those needing broader JavaScript support, a generic server might be more suitable.

Question 4

How to fix template linting not working in Ember Language Server?

Accepted Answer

First, ensure ember-template-lint is added as a dependency in your project's package.json. If issues persist, check that your project uses the classic Ember CLI structure, as pods are unsupported, and verify the ELS configuration in your editor for any path or setting errors.

Question 5

Can I use Ember Language Server with Neovim?

Accepted Answer

Yes, through plugins like coc-ember or native LSP integration in nvim-lspconfig. Configure the plugin to point to the ELS server entry point, and it should provide features similar to other editors, though setup might require additional steps compared to VSCode.

Question 6

What addons are available for Ember Language Server and how do I install them?

Accepted Answer

Addons like els-addon-glint for Glint integration or els-a11y-addon for accessibility checks can be installed as dev-dependencies in your project. For global installation, specify the addon path in your LS editor settings, as detailed in the README for custom configurations.

Question 7

Why isn't Ember Language Server supporting my pods structure?

Accepted Answer

ELS currently only supports the default classic structure in Ember CLI applications; pods are not supported yet, as stated in the README. You may need to convert to classic structure or wait for future updates that might add pods compatibility.
