# Code Intelligence **(FREE)**
|
|
|
|
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/1576) in GitLab 13.1.
|
|
|
|
Code Intelligence adds code navigation features common to interactive
|
|
development environments (IDE), including:
|
|
|
|
- Type signatures and symbol documentation.
|
|
- Go-to definition.
|
|
|
|
Code Intelligence is built into GitLab and powered by [LSIF](https://lsif.dev/)
|
|
(Language Server Index Format), a file format for precomputed code
|
|
intelligence data.
|
|
|
|
NOTE:
|
|
You can automate this feature in your applications by using [Auto DevOps](../../topics/autodevops/index.md).
|
|
|
|
## Configuration
|
|
|
|
Enable code intelligence for a project by adding a GitLab CI/CD job to the project's
|
|
`.gitlab-ci.yml` which generates the LSIF artifact:
|
|
|
|
```yaml
|
|
code_navigation:
|
|
image: sourcegraph/lsif-go:v1
|
|
allow_failure: true # recommended
|
|
script:
|
|
- lsif-go
|
|
artifacts:
|
|
reports:
|
|
lsif: dump.lsif
|
|
```
|
|
|
|
The generated LSIF file size may be limited by
|
|
the [artifact application limits (`ci_max_artifact_size_lsif`)](../../administration/instance_limits.md#maximum-file-size-per-type-of-artifact),
|
|
default to 100MB (configurable by an instance administrator).
|
|
|
|
After the job succeeds, code intelligence data can be viewed while browsing the code:

## Language support
|
|
|
|
Generating an LSIF file requires a language server indexer implementation for the
|
|
relevant language.
|
|
|
|
| Language | Implementation |
|
|
|---|---|
|
|
| Go | [`sourcegraph/lsif-go`](https://github.com/sourcegraph/lsif-go) |
|
|
| JavaScript | [`sourcegraph/lsif-node`](https://github.com/sourcegraph/lsif-node) |
|
|
| TypeScript | [`sourcegraph/lsif-node`](https://github.com/sourcegraph/lsif-node) |
|

|
|
refer to their documentation to see how to generate an LSIF file for your specific language.
