Welcome to Bit's new open-source website!

Update Components

A component's source of truth is not is any specific workspace but in its remote scope. When collaborating on components it may happen that a newer version is available for a component maintained in your workspace.

To get new snaps for components maintained in your workspace, run:

$bit
Copiedcopy

Alternatively, run bit install to install the workspace dependencies and import new component snaps, in a single command.

The output lists all updated components. These updates are stored in the local scope. They are not checked-out to the working directory, yet.

successfully imported 1 components, 0 components are up to date
- updated my-org.tasks-scope/apps/to-do 2 new version(s) available, latest 0.0.3

When collaborating on a workspace using VCS like git, it may happen that new components are added to the workspace (the .bitmap file, which is tracked by your VCS, has additional components registered):

successfully imported 1 components, 0 components are up to date
- added my-org.tasks-scope/hooks/use-todo 2 new version(s) available, latest 0.0.2, currently used version 0.0.2

Components with pending updates are also listed when running bit status.

Compare component snaps

Bit uses git to evaluate differences snaps. To compare between two snaps, or between a snap and the component's local (un-snapped) changes, run:

$bit
Copiedcopy
See full command options

The following output lists the differences between the checked-out snap and the local changes. Differences between versions can include dependencies and configuration, in addition to the component's source files.

Alternatively, head over to the 'compare' tab in the UI (scope or workspace) to visually inspect changes:

Checkout snaps to the working directory

To checkout a component's head (latest snaps) to the working directory, run the following:

$bit
Copiedcopy
See full command options

The output lists the component files that were updated by this checkout:

successfully switched teambit.design/info/icon-text to version head

updated icon-text.composition.tsx
updated icon-text.docs.mdx
updated icon-text.module.scss
updated icon-text.tsx
updated index.ts

Handling merge conflicts

In cases where auto-merge is impossible, you wil be prompted with the following message:

automatic merge has failed for component info/text-icon
please use "--manual" to manually merge changes or use "--theirs / --ours" to choose one of the conflicted versions

To resolve these conflicts, run the checkout command again with one of these options:

  • --theirs - accept incoming changes
  • --ours - keep local changes
  • --manual - resolve conflicts, manually

For example:

$bit
Copiedcopy
