scip-typescript

SCIP indexer for TypeScript and JavaScript.

Quick start

Installation

npm install -g @sourcegraph/scip-typescript

Currently, Node v14, Node v16 and Node v18 are supported.

Indexing a TypeScript project

Navigate to the project root, containing tsconfig.json.

npm install # or yarn install
scip-typescript index

Indexing a JavaScript project

Navigate to the project root, containing package.json.

npm install # or yarn install
scip-typescript index --infer-tsconfig

To improve the quality of indexing results for JavaScript, consider adding @types/* packages as devDependencies in package.json.

Index a TypeScript project using Yarn workspaces

Navigate to the project root, containing package.json.

yarn install

scip-typescript index --yarn-workspaces # For Yarn v2
scip-typescript index --yarn-berry-workspaces # For Yarn v3 (Berry)

Indexing in CI

Add the following run steps to your CI pipeline:

npm install -g @sourcegraph/scip-typescript @sourcegraph/src
npm install # or yarn install
scip-typescript index
# Upload index with any necessary tokens (shown here using GitHub workflow syntax)
src lsif upload -github-token='${{ secrets.GITHUB_TOKEN }}' -no-progress

For more examples, see the Sourcegraph docs.

Migrating from lsif-node

Before creating scip-typescript, we used another TypeScript indexer called lsif-node. We recommend migrating to scip-typescript if you are using lsif-node.

Follow the steps below to migrate from lsif-node to scip-typescript:

• Replace usages of the lsif-tsc -p ARGUMENTS command with scip-typescript index ARGUMENTS.
• Upgrade to the latest version of the src command-line interface, which you can install via yarn global add @sourcegraph/src. It’s okay if the version of your src command-line interface does not match the version of your Sourcegraph instance.
