Building Offline-First Apps with LitebaseOffline-first design treats intermittent or absent network connectivity as the default rather than an exception. For many mobile, desktop, and IoT applications, the ability to function smoothly without a connection is essential for good user experience and reliability. Litebase — a lightweight embedded database designed for modern apps — fits naturally into this approach. This article explains the principles of offline-first architecture, how Litebase supports those patterns, and practical guidance for building robust offline-capable applications.

---

Why offline-first matters

• Improved reliability: Users can continue to read, create, and update data without waiting for network availability.
• Faster perceived performance: Local reads and writes are near-instant compared to remote requests.
• Better UX in poor networks: Offline-first apps avoid errors and data loss when connections drop.
• Broader reach: Apps that work offline serve users in regions with limited connectivity.

---

Core offline-first patterns

1. Local storage as the source of truth
   Store application state locally and treat the local store as the canonical model. Network synchronization becomes a secondary concern, reconciling local changes with remote servers.

2. Optimistic UI and local transactions
   Apply user changes immediately to the local store and show them in the UI right away, while synchronizing in the background. This requires conflict handling and rollback strategies.

3. Change tracking and sync queues
   Record mutations (creates, updates, deletes) in a durable change-log or queue so they can be retried and reconciled with the server when connectivity returns.

4. Conflict resolution strategies
   Decide on deterministic conflict resolution: last-write-wins (LWW), merge strategies, CRDTs, or server-side authoritative resolution depending on your domain.

5. Background sync and connectivity awareness
   Detect network availability and schedule syncs opportunistically (e.g., when on Wi‑Fi, charging, or idle). Use exponential backoff for retries.

---

How Litebase supports offline-first apps

• Embedded and lightweight: Litebase runs in-process on mobile and desktop platforms, providing fast local reads/writes without a separate server process.
• ACID-like local transactions: Litebase supports transactional operations so groups of changes are atomic locally.
• Durable storage: Data persists across app restarts, so queued changes are not lost.
• Simple change-tracking: Use Litebase APIs to record mutations or to watch for local changes to build a synchronization layer.
• Small footprint and fast startup: Useful for resource-constrained devices and apps that need quick responsiveness.

---

Data model and schema design

• Denormalize for offline speed: Fewer joins and more self-contained records reduce the need for multiple round trips during sync.

• Include metadata fields: Add version numbers, lastModified timestamps, and a clientId/userId for each record to aid conflict resolution. Example fields:

  • id
  • data…
  • lastModified (ISO 8601 timestamp)
  • version (incrementing integer or vector clock)
  • pending (boolean) or changeLogId

• Partition user and global data: Keep per-user data separate from shared/global data so sync logic can be scoped.

---

Implementing local-first workflows with Litebase

1. Initialize local store and seed data
   On app startup, open the Litebase database and load local state. If first run and network available, seed from server.

2. Apply changes locally (optimistic updates)
   Wrap mutations in Litebase transactions so they commit locally immediately:

   • Update UI instantly from the local store.
   • Append a change record to a durable queue (table) with type, payload, timestamp, and status.

3. Background synchronization loop

   • Monitor connectivity and app lifecycle events.
   • When appropriate, read pending changes from the queue and send batched requests to the server.
   • Upon successful ack, mark local change records as synced and update any server-assigned fields (e.g., serverId, canonical timestamp).
   • On failure, use exponential backoff and preserve changes for retry.

4. Handling remote updates

   • Periodically fetch server changes (delta since last sync) and merge into Litebase.
   • Use version or timestamp comparison to detect conflicts; apply your chosen conflict resolution strategy.

---

Conflict resolution approaches

• Last-write-wins (LWW): Simple and common; accept the change with the newest timestamp. Works when causality isn’t critical.
• Field-level merging: Merge non-conflicting fields from both versions; useful for records where different actors update different fields.
• Operational transforms / CRDTs: For collaborative editing scenarios where merges should be deterministic and preserve all edits.
• Server authoritative: Let the server decide on final state and propagate resolved state back to clients.

Tip: Always surface resolved conflicts to users when automatic resolution might cause data loss, or provide an “undo” history.

---

Example sync flow (high level)

1. User edits record locally; Litebase commits change and adds an entry to change_queue.
2. Sync worker wakes (connectivity available) and batches items from change_queue.
3. Worker POSTs batch to server sync endpoint.
4. Server responds with success and canonical versions for records.
5. Client updates local records in a transaction: set synced=true, update version/lastModified, remove change_queue entries.
6. If server reports conflicts, apply resolution policy and write resolved record back to Litebase.

---

Practical tips and pitfalls

• Batch network calls: Group changes into reasonable batches to reduce overhead.
• Keep sync idempotent: Include change IDs so retries don’t duplicate actions server-side.
• Limit change log size: Compact or checkpoint the change queue after successful sync to prevent unbounded growth.
• Secure data at rest: Encrypt sensitive local data if device compromise is a concern.
• Test under adverse conditions: Simulate flaky networks, app restarts mid-sync, and multi-client conflicts.
• Consider storage limits: On low-storage devices, prioritize essential data and provide eviction strategies.

---

Example technologies to combine with Litebase

• Service workers (web): Use Litebase in web apps with service workers for background sync and offline caching.
• Background tasks (mobile): Use iOS/Android background fetch or WorkManager to schedule syncs.
• Push notifications/webhooks: Use server-initiated push to tell clients there are remote updates to fetch.
• Encryption libraries: For local encryption of sensitive fields.

---

Measuring success

Track metrics that show offline-first health:

• Time-to-local-commit (how fast UI reflects user changes).
• Sync queue length and average time-to-sync.
• Number of conflicts per time period and conflict resolution outcomes.
• Data loss incidents (should be zero).
• User engagement in low-connectivity environments.

---

Conclusion

Litebase provides the building blocks for offline-first apps: an embedded, durable local store with transactional semantics and small footprint. Pair it with a thoughtful sync architecture (change queues, optimistic UI, robust conflict resolution, and background sync) to deliver apps that stay responsive and reliable regardless of network quality. Design for durability, idempotency, and clear conflict policies, and test extensively under real-world failure modes to ensure a smooth offline experience.

How to Run Advanced Regression Models in jamovi (Step‑by‑Step)Regression analysis is a cornerstone of quantitative research. jamovi provides an approachable, GUI-driven environment for running standard and advanced regression models without extensive coding. This article walks through setting up your data, choosing appropriate models, running analyses, checking assumptions, interpreting outputs, and extending jamovi with add‑modules for advanced techniques.

---

Overview: What counts as “advanced” regression in jamovi

Advanced regression analyses include:

• Multiple and hierarchical (multilevel) linear regression
• Generalized linear models (GLMs) (logistic, Poisson, negative binomial)
• Mixed‑effects models (linear mixed models, generalized mixed models)
• Regularized regression (LASSO, ridge)
• Robust regression and bootstrapped inference
• Model selection, comparison, and diagnostics

jamovi supports many of these natively and via add‑modules (e.g., GAMLj, MixedModels, glmnet, psych/robust packages). Below we cover step‑by‑step workflows for several common advanced scenarios.

---

1. Prepare your data

1. Open jamovi and load your dataset: File → Open → choose CSV, Excel, or jamovi (.omv).
2. Inspect variable types in the Data tab. Ensure:
   • Continuous variables are numeric.
   • Categorical variables are nominal/factor (set as “nominal” or “ordinal” as appropriate).
3. Create derived variables if needed: Transform → Compute.
   • Center predictors (mean‑center) for interaction terms to reduce multicollinearity: Compute → (X – mean(X)).
4. Handle missing data:
   • Use Filter to run analyses on complete cases, or consider multiple imputation (use the jamovi module mice or conduct imputation externally).
5. Check distributions with Descriptives and Plots to spot outliers and skewness.

---

2. Multiple linear regression (with interactions and centering)

Use this when your outcome is continuous and residuals are approximately normal.

Steps:

1. Analyses → Regression → Linear Regression.
2. Move the dependent variable into “Dependent Variable.”
3. Add predictors to “Covariates” and categorical predictors to “Factors.”
4. For interaction terms: click the little cog (model) → Model → add interaction(s) between predictors.
5. To mean‑center a predictor, create a new variable: Transform → Compute → X_center = X – mean(X).
6. Under Options, request:
   • Estimates, Confidence intervals, Standardized coefficients (if desired).
   • Model fit statistics: R², adjusted R², AIC.
   • Plots: residuals vs. fitted, Q–Q plot.
7. Interpret coefficients: unstandardized b (unit change), p-values, and CIs. For interactions, probe simple slopes or plot predicted values.

Diagnostics:

• Check Variance Inflation Factor (VIF) for multicollinearity: Options → Collinearity diagnostics.
• Examine residual plots for heteroscedasticity and nonlinearity.
• If heteroscedasticity appears, use robust standard errors (Options → Robust standard errors).

---

3. Generalized linear models (logistic, Poisson)

Use GLMs when outcomes are non‑normal (binary counts, rates).

Logistic regression (binary outcome):

1. Analyses → Regression → Generalized Linear Model.
2. Put outcome in “Dependent Variable” and set “Family” = Binomial, “Link” = Logit.
3. Add predictors as covariates/factors.
4. Options: display Odds Ratios (exp(B)), CIs, model fit (AIC), classification table, ROC curve.
5. Check for separation and sparse categories; consider Firth correction via add‑modules if needed.

Poisson / negative binomial (count outcomes):

1. In the GLM dialog, choose Family = Poisson for counts.
2. If overdispersion exists (variance > mean), try negative binomial (if available via module) or use quasi‑Poisson alternatives.
3. Include an offset term for rates (log of exposure) if modeling rates: in GLM specify Offset = log(exposure variable).

Model assessment:

• Use Deviance, AIC, and residual diagnostics (e.g., deviance residuals).
• For logistic models, report classification metrics and the ROC/AUC.

---

4. Mixed‑effects models (multilevel / hierarchical)

Use mixed models when data are clustered (e.g., students nested in schools, repeated measures).

Install the MixedModels or GAMLj module if not present: Modules → jamovi library → search and install (MixedModels, GAMLj).

Linear mixed model (continuous outcome):

1. Analyses → Mixed Models → Linear Mixed Model (or GAMLj → Linear Mixed Models).
2. Dependent Variable → outcome; Fixed Effects → predictors.
3. Specify random effects: add grouping variable (e.g., Subject, School) and choose random intercepts and/or slopes.
4. Choose estimation method (REML for comparing random structures, ML for comparing fixed effects).
5. Request covariance structures and report intraclass correlation (ICC).
6. Interpret fixed effects like regression coefficients; random effect variance components tell how much variability is at each level.

Generalized mixed model (non‑normal outcomes):

1. Analyses → Mixed Models → Generalized Mixed Model; choose appropriate family (Binomial, Poisson).
2. Configure random effects similarly.
3. Assess model convergence warnings and consider simplifying random structure if convergence fails.

Model checking:

• Plot residuals by group; examine random effects BLUPs.
• Compare nested models with likelihood ratio tests (ML) or use AIC/BIC.

---

5. Regularized regression (LASSO, ridge)

Useful when predictors are many and multicollinearity or variable selection is needed.

Install the glmnet or jfa package via Modules → jamovi library.

Steps:

1. Analyses → glmnet (or Regularization module).
2. Specify outcome and predictor matrix.
3. Choose penalty: LASSO (L1), ridge (L2), or elastic net.
4. Use cross‑validation (CV) to pick lambda (regularization strength). Request k‑fold CV (commonly k=10).
5. Extract selected predictors (nonzero coefficients at chosen lambda) and CV error plots.

Interpretation:

• Coefficients are biased toward zero; focus on predictive performance (CV error) rather than unbiased effect estimation.

---

6. Robust regression and bootstrapping

Robust regression reduces influence of outliers; bootstrapping provides empirical CIs.

Robust regression:

• Use Modules → Robust regression / GAMLj’s robust options.
• Choose robust estimator (Huber, MM) and compare with OLS.

Bootstrapping:

1. Many jamovi analyses include a Bootstrapping option in the options panel—enable it.
2. Specify number of bootstrap samples (e.g., 1000).
3. Use bootstrap CIs for coefficients and other statistics (percentile/bootstrap‑t).

---

7. Model comparison, selection, and reporting

Model comparison:

• Compare nested models with Likelihood Ratio Tests (for ML/REML appropriately) or ANOVA-like model comparison where supported.
• Use information criteria (AIC, BIC) for non‑nested comparisons.

Model selection:

• Stepwise selection is discouraged; prefer theory‑driven models or regularization with CV to select predictors.
• Report effect sizes, CIs, and model performance (R² or pseudo‑R² for GLMs, AUC for binary outcomes).

Reporting checklist (concise):

• Data and pre‑processing (missing data handling, transformations).
• Model family and link function.
• Fixed and random effects structure.
• Estimation method (ML/REML) and software/module used (include jamovi version and modules).
• Key coefficients with CIs, p‑values, and model fit indices.
• Diagnostics performed (collinearity, residuals, influence).

---

8. Example: Step‑by‑step — logistic mixed model for repeated binary outcomes

1. Load dataset with repeated responses per Subject.
2. Modules → install MixedModels (if needed).
3. Analyses → Mixed Models → Generalized Mixed Model.
4. Set Family = Binomial, Link = Logit. Dependent = binary outcome.
5. Fixed effects: time, treatment, covariates.
6. Random effects: add Subject as random intercept; add random slope for time if theory suggests.
7. Choose estimation (Laplace or adaptive Gauss‑Hermite where available).
8. Run model; inspect fixed effect coefficients (log odds), convert to odds ratios (exp(coef)), and check random effect variances.
9. Assess convergence, plot predicted probabilities by group and time, and report AIC/BIC.

---

9. Extending jamovi: useful modules and resources

Useful jamovi modules:

• GAMLj — flexible linear, generalized linear, and mixed models with friendly output.
• MixedModels — for more advanced multilevel models.
• glmnet — LASSO/ridge.
• mirt / psych — psychometric and factor analysis tools.
• mice — multiple imputation.

Resources:

• jamovi user guide and module documentation (within jamovi library).
• Tutorials and example datasets in the jamovi community.

---

10. Troubleshooting tips

• Convergence failures: simplify random structure, increase iterations, or rescale predictors.
• Overdispersion in counts: switch to negative binomial or use quasi‑Poisson.
• Separation in logistic models: check sparse cells; consider Firth regression or penalized likelihood.
• High VIFs: center predictors, combine correlated predictors, or use regularization.

---
