Tide Layer

Table of ContentsClose

1. Description

This layer installs tide package which allows communication with standalone typescript server tsserver for JavaScript/TypeScript development.

1.1. Features:

  • First class support from tsserver just like vscode: speed and accuracy
  • Linter
  • Refactor
  • Go to definition
  • Find references

2. Install

See tide for details. First you must have `tsserver` installed in your project or globally:

npm install -g typescript

Next enable this layer in your ~/.spacemacs. You will need to add tide to the existing dotspacemacs-configuration-layers list in this file. Then set the backend variables for JavaScript layer, React layer and TypeScript layer to tide in dotspacemacs-configuration-layers

(javascript :variables
             javascript-backend 'tide)

(typescript :variables
            typescript-backend 'tide)

Both javascript-backend and typescript-backend can be set per project.

When using this layer, make sure tsconfig.json or jsconfig.json is present in the root folder of the project.

Example from emacs tide package: For JavaScript projects you may want to create jsconfig.json in the root folder of your project. jsconfig.json is tsconfig.json with allowjs attribute set to true.

  "compilerOptions": {
    "target": "es2017",
    "allowSyntheticDefaultImports": true,
    "noEmit": true,
    "checkJs": true,
    "jsx": "react",
    "lib": [ "dom", "es2017" ]

Without this file tsserver will pick up current folder as project root.
